Semiconductor Device is an electronic circuit element made from a material that is neither a healthy conductor nor a solid insulator; hence called a semiconductor. Such devices have found widespread applications because of their ruggedness, robustness, and affordability. As individual components, they have found use in power devices, optical sensors, and light emitters, including solid-state lasers. They have an extensive range of current and voltage handling functionality, with current ratings from a few nanoamperes (10−9 ampere) to more than 5,000 amperes and voltage ratings extending above 100,000 volts. More importantly, semiconductor devices lend themselves to integration into complicated but readily makeble microelectronic circuits.

The field of physics that deals with the macroscopic physical properties of matter is called condensed matter physics. Specifically, it is worried about "condensed" phases that show up whenever the quantity of particles in a system is very huge and the collaborations between them are strong. Condensed States of Matter. Condensed states of matter are solids and liquid - states in which the atoms or molecules are fairly close together and their behaviour is determined (at least in part) by the attractions between them.

Thermodynamics is the part of physics that manages heat and temperature, and their relation to work, radiation, energy, and matter properties. Statistical physics is a part of physics where the methods like statistics, probability theory and particularly the mathematical tools will be used in solving out the large populations, approximations, and physical problems.

Radiation is naturally present in our environment, it can have either beneficial or harmful effects, depending on its use and control. For that reason, Congress charged the U.S. Nuclear Regulatory Commission (NRC) with protecting people and the environment from unnecessary exposure to radiation as a result of civilian uses of nuclear materials. Toward that end, the NRC requires nuclear power plants; research reactors; and other medical, industrial, and academic licensees to use and store radioactive materials in a way that eliminates unnecessary exposure and protects radiation workers and the public.

Photonics is the physical science of light (photon) generation, detection, and manipulation through emission, transmission, modulation, signal processing, switching, amplification, and sensing. Though covering all light's technical applications over the whole spectrum, most photonic applications are in the range of visible and near-infrared light. The term photonics developed as an outgrowth of the first practical semiconductor light emitters invented in the early 1960s and optical fibers developed in the 1970s.

Nuclear Physics is the field of science that studies about atomic nuclei, constituents and interactions. Nuclear Physics on the other hand, apprehensions itself with the particles of the nucleus called nucleons (protons & neutrons). The research in this field has led to many applications such as  nuclear power, nuclear weapons, nuclear medicine, nuclear magnetic resonance imaging. The modern nuclear physics includes nuclear fusion, nuclear fission, nuclear decay and Production of "heavy" elements using atomic number greater than five.

Nanotechnology is defined by size is naturally very broad, including fields of science as diverse as surface science, organic chemistry, molecular biology, semiconductor physics, energy storage,[3][4] microfabrication, molecular engineering, etc. Nanotechnology ("nanotech") is manipulation of matter on an atomic, molecular, and supramolecular scale. Nanotechnology may be able to create many new materials and devices with a vast range of applications, such as in nanomedicine, nanoelectronics, biomaterials energy production, and consumer products. On the other hand, nanotechnology raises many of the same issues as any new technology, including concerns about the toxicity and environmental impact of nanomaterials and their potential effects on global economics.

Quantum theory is the theoretic basis of modern physics which explains the nature and the behaviour of matter and energy in the atomic as well as subatomic level. The nature and the performance of matter and energy at that level is referred as quantum physics. Quantum physics is the science of small things in which the quantum reality has an effect. Quantum is mentioned as discrete amount or portion. One of the most unexpected and controversial aspects of quantum physics is that it’s impossible to determine with certainty the outcome of a single experiment on a quantum system.

The force of attraction or repulsion acting from a distance is defined as Magnetism. Magnetic field is generated by the movement of electrically charged particles. It is essential in magnetic objects such as magnet. There are two poles in a magnet- North (N) and South (S) poles. Opposite poles of two magnets will attract each other and each will repel the like pole of the other magnet. Diverse varieties of magnetism lead some magnets to attract and others to repel. Magnetism symbolizes to the attraction of iron and other metals in magnets and electric currents.

The role of the Medical Physics subsection in Current Oncology is to provide information and evaluations of these exciting developments in image-guided adaptive radiation therapy. Current Oncology also publishes critical evaluation studies of the clinical implementation and effect of novel and clinically established technologies. Medical physics is, usually speaking, the application of physics concepts, theories and methods to medicine or healthcare.

Astrophysics is an extension of classical Astronomy which deals with the celestial bodies and phenomena. Astrophysics can also be defined as the combination of Astronomy and Physics. Some areas where we can see the applications of research in astronomy are electronics, advanced computing, communication satellites, optics, solar panels and MRI Scanners.  Even though it takes time before an application of a research in astrophysics finds its way into our daily life, the impact it eventually makes is worth the wait.

The interaction of the supersonic solar wind with the Earth’s dipole magnetic field is surprisingly complicated. About 5 orders of magnitude of spatial scales are involved in the global behaviour of the magnetospheric system and timescales from seconds for the auroral pulsations to several minutes for the reaction of the global magnetosphere to solar-wind pressure changes to several days for the intensification of the electron radiation belt to years for the decay of relativistic electrons. Plasma-physical length scales vary from a Debye length of 0.4 cm in the ionosphere to ion gyro radii of 1000 km in the magnetotail and in the ion radiation belt; plasma-physical timescales associated with wave substructure can also be very short.

Geophysics manages a wide cluster of geologic wonders, including the temperature dispersion of the Earth's inside; the source, design, and varieties of the geomagnetic field; and the huge scale highlights of the earthbound hull, for example, breaks, mainland sutures, and mid-maritime edges. Present day geophysical research stretches out to wonders of the external pieces of the Earth's air (e.g., the ionospheric dynamo, auroral electrojets, and magnetopause flow framework) and even to the physical properties of different planets and their satellites.

Matter does not simply pull on other matter across empty space, as Newton had fancied. Rather matter garbles space-time and it is this garbled space-time that in turn impacts other matter. Objects (including planets, like the Earth, for instance) fly freely under their own inertia through space-time, following curved paths because this is the shortest possible path (or geodesic) in twisted space-time.
