The military and aerospace electronics industries are experiencing an ever increasing demand for the use of plastic encapsulated microcircuits and semiconductors. While plastic encapsulated microcircuits and semiconductors offer a number of inherent advantages over hermetically sealed ceramic packages, uncontrolled use can introduce a number of technical risks in military and aerospace equipmen...

Some problems involved in the interpretation of Hall-effect measurements in polycrystalline semiconductors have not been resolved, especially when the contribution of the boundaries is appreciable. Using the Herring theory of transport properties in inhomogeneous semiconductors, we present an alternative interpretation to that previously proposed. This model permits the calculation of the Hall ...

A new structure for isolator is proposed in this work. The proposed structure consists of metamaterial-magnetoplasma semiconductors parallel plate structure. The utility of magnetoplasma semiconductors is promising in developing nonreciprocal components in the submillimeter-wave and millimeter-wave bands for satellite communications. Metamaterials (MTMs) is used to enhance the behavior of the i...

Organic electronics is now entering its second decade as a commercial technology but in many ways is a relatively recent and emerging field. As such, significant advances are being made across a broad range of activities, from improving the understanding of very fundamental phenomena to improving manufacturing technologies. Much of the interest in organic electronics stems from the chemical tun...

Some examples of space-borne applications that require improvements in detector technology compared with conventional Si and Ge designs are described. Properties of compound semiconductors are noted, and a range of different detector developments are briefly reviewed. Material fabrication improvements for several compound semiconductors have resulted in near Fano-limited performance.
