A dielectric (or dielectric material) is an electrical insulator that can be polarized by an applied electric field. When a dielectric is placed in an electric field, electric charges do not flow through the material as they do in an electrical conductor but only slightly shift from their average equilibrium positions causing dielectric polarization. Because of dielectric polarization, positive charges are displaced in the direction of the field and negative charges shift in the opposite direction. This creates an internal electric field that reduces the overall field within the dielectric itself. If a dielectric is composed of weakly bonded molecules, those molecules not only become polarized, but also reorient so that their symmetry axes align to the field.
Electronics is widely used in information processing, telecommunication, and signal processing. The ability of electronic devices to act as switches makes digital information-processing possible. Interconnection technologies such as circuit boards, electronics packaging technology, and other varied forms of communication infrastructure complete circuit functionality and transform the mixed electronic components into a regular working system, called an electronic system; examples are computers or control systems. An electronic system may be a component of another engineered system or a standalone device. As of 2018 most electronic devices use semiconductor components to perform electron control.
Materials Science and Engineering can sub discipline as Materials Science and Materials Engineering. "Materials science" researches the connections that exist between the structures and properties of materials. Conversely, "materials building" is, based on these structure– property connections, planning or designing the structure of a material to deliver a foreordained arrangement of properties. It is the plan and disclosure of new materials, especially solids. For all intents and purposes exceptionally critical properties of strong materials might be assembled into six distinct classes: mechanical, electrical, warm, attractive, optical, and deteriorative. For each there is a trademark sort of boost fit for inciting diverse reactions. Mechanical properties relate distortion to a connected burden or power; models incorporate versatile modulus and quality. For electrical properties, for example, electrical conductivity and dielectric consistent, the upgrade is an electric field. The warm conduct of solids can be spoken to as far as warmth limit and warm conductivity. Attractive properties exhibit the reaction of a material to the use of an attractive field. For optical properties, the improvement is electromagnetic or light radiation; record of refraction and reflectivity are agent optical properties. At last, deteriorative attributes identify with the substance reactivity of materials.
Instrumentation is a collective term for measuring instruments that are used for indicating, measuring and recording physical quantities such as flow, temperature, level, distance, angle, or pressure. The term has its origins in the art and science of scientific instrument-making. Instrumentation can refer to devices as simple as direct-reading thermometers, or as complex as multi-sensor components of industrial control systems. Today, instruments can be found in laboratories, refineries, factories and vehicles, as well as in everyday household use (e.g., smoke detectors and thermostats)

For any electronic device to operate well, electrical current must be efficiently controlled by switching devices, which becomes challenging approach to systems very small dimensions. This problem must be addressed by synthesizing materials that permit reliable turn-on and turn-off current at any size scale. New electronic and photonic nanomaterials assure dramatic breakthroughs in communications, computing devices and solid-state lighting. Current research involves bulk crystal growth, organic semiconductors, thin film and nanostructure growth, and soft lithography. Many major photonics companies in the world views on different technologies and opinions about future challenges for manufacturers and integrators of lasers and photonics products. The silicon photonics market is anticipated to grow to $497.53 million by 2020, expanding at a CAGR of 27.74% from 2014 to 2020. The silicon carbide semiconductor market is estimated to grow $3182.89 Million by 2020, at an expected CAGR of 42.03% from 2014 to 2020.
The study of physical and chemical process that rises by incorporation of two phases, with solid–liquid/ solid–gas/ solid–vacuum/ liquid–gas interfaces is named as Surface Science. The actual application of surface science in related arenas like chemistry, mechanical engineering, electrical engineering and physics is recognized as Surface Engineering. Surface Chemistry achieves the alteration of chemical configuration of a surface by presenting functional groups and additional elements while Surface physics deals with the physical deviations that arise at interfaces. Techniques tangled in Surface engineering are spectroscopy methods such as X-ray photoelectron spectroscopy, low-energy electron diffraction, electron energy loss spectroscopy, Auger electron spectroscopy, Thermal desorption spectroscopy, ion scattering spectroscopy and secondary ion mass spectrometry, etc. The chemical reactions at the interface is generally termed as Surface Chemistry and is also linked to surface engineering. It is very significant in the arenas of heterogenous catalysis, electrochemistry and geochemistry
