A long‐wavelength λc=18 μm infrared hot‐electron transistor (IHET) with low dark current is demonstrated. In order to achieve long‐wavelength absorption, a low barrier height is required, which in turn results in a large dark current. Therefo

Solid‐state interfacial reactions between self‐supporting thin (50, 100, and 200 A) films of Ni and Co, and amorphous (a) films of SiC, Si and C were investigated in the 300–1000 °C temperature range. The metastable solubility of C (from SiC)

The origin of current reduction in an infrared hot‐electron transistor is examined by studying the thermal activation energy of the emitter and the collector dark current as a function of emitter bias Ve. For the emitter, the activation energy Eae

The mechanical and corrosion properties of most metal matrix composites (MMCs) are critically affected by the interfacial reactions between the matrix and the fiber or reinforcement medium. These reactions can be beneficial (i.e., increase the streng
