Physicalelectronics Applications

The study of physical phenomena basic to electronics, such as discharges, thermionic and field emission, and conduction in semiconductors and metals. Physical Electronics deals with the actual phenomenon occurring within the device during its operation. However, in the part of electronics, we study how an electronic device actually works. On the other hand, electronic engineering is the application part of core electronics and under this section, we deal with successive development. Finally electronics can be defined as "the field of science and engineering which deals with electronic devices and its utilization". The composition of the outer most atomic layers of a material plays a critical role in properties such as: chemical activity, adhesion, wettability, electrostatic behavior, corrosion resistance, bio-compatibility, etc. In addition, contaminants, process residues, diffusion products, and impurities are typically present at the surface of solid samples or at the interfaces of thin film structures. The ability to characterize thin film structures, via sputter depth profiling, provides a unique opportunity to examine materials used in thin layers and to study their interaction with materials in adjacent layers. The ability to analyze sub-micron features, defects, or particulate contaminants is of critical importance to increasing product yield in a number industrial applications including: semiconductor device fabrication, hard disk read/write head fabrication, specialty mirrors, composite materials, etc.
