A copper‐related shallow acceptor complex has been discovered in germanium single crystals grown in vacuum and doped with arsenic and copper. Photothermal ionization spectroscopy of samples quenched from 673 K reveals two sets of hydrogenic lines w

There are a wide variety of products that depend on a Pressure- Sensitive Adhesive (PSA) for their ability to function. These products have varying degrees of complexity, which are usually determined by the sophistication of their end use. In general

We present strong experimental evidence suggesting that we have synthesized the \ensuremath{\beta}-${\mathrm{C}}_{3}$${\mathrm{N}}_{4}$ phase. This is a material predicted by theory to have bulk moduli comparable to diamond. Thin films containing sma

DX centers in Al{sub 0.38}Ga{sub 0.62}As doped with Te have been studied by Deep Level Transient Spectroscopy (DLTS) as a function of uniaxial stress. No splitting nor broadening of the DLTS peaks were observed. However, the peak positions and height

We have studied the {beta} spectrum of {sup 14}C using a germanium detector containing a crystal with {sup 14}C dissolved in it. We find a feature in the {beta} spectrum 17 keV below the end point which can be explained by the hypothesis that there i

Far‐infrared properties of a two‐layer structure consisting of an ion‐implantation doped layer on a thin ultrapure slice of germanium have been studied. Photoresponse extends beyond the shallow impurity absorption edge at 120 μm to about 192

We report on the development of Germanium Blocked Impurity Band (BIB) photoconductors for long wavelength infrared detection in the 100 to 250.μm region. Liquid Phase Epitaxy (LPE) was used to grow the high purity blocking layer, and in some cases,

We demonstrate a reversible phase transition in nanoparticles composed of a binary eutectic alloy, Ge–Au. The structure, 9 nm diameter nanoparticles embedded in silica, can be switched from bilobe to mixed using a 30 ns ultraviolet laser pulse. The
