The maturation of the III-V materials technology has provided an opportunity for the development of a producible and affordable class of IR detector arrays. Designs based on the GaAs compounds permit the realization of multiple quantum well IR photod

A three‐level Shockley–Read model for p‐type Hg vacancy‐doped HgCdTe is proposed which leads to an accurate prediction of excess carrier lifetime versus temperature. The three levels included in the model are the two shallow Hg vacancy accept

Results are presented for the temperature and frequency dependence of the attenuation of two piezoelectrically active ultrasonic waves in ZnO: (1) compressional waves propagated along the c axis, and (2) shear waves propagated normal to the c axis an

Ultrasonic attenuation studies in dilute superconducting Nb-Zr alloys revealed strongly temperature-dependent absorption peaks that cannot be explained in terms of single electron-phonon scattering processes. The set of temperatures at which these pe

In a study of the influence of materials preparation parameters on the thermodynamic properties of superconductors, detailed information concerning the effective limiting superconducting energy gap, Δ(0), of doped Sn has been obtained from measureme

A semi-empirical formalism is presented for the calculation of transition temperature, thermodynamic critical field, and specific heat in dilute alloys of type 1 superconductors. The calculation is based on an extension of a ‘local strain field’

A semi-empirical formalism is developed to account for the detailed dependence of the superconducting transition temperature of dilute alloys on solute concentration. A mismatch of solute and solvent ion sizes causes small strain fields in the region

Measurements were made of the ultrasonic shear wave attenuation in superconducting aluminum, using 99.999% pure single crystals with parallel faces in the [100], the [110], and the [111] directions. It was found that the temperature dependence of the

The temperature dependence of the attenuation of compressional ultrasonic waves has been measured in high‐purity single crystals of superconducting Sn. Deviations from BCS behavior have been observed. The experimental results are compared on the ba

Recent ultrasonic-attenuation studies have led to conflicting interpretations concerning the reduced anisotropy of the superconducting energy gap characteristic of impure Sn. Perz and Dobbs have concluded that the reduced anisotropy is only due to an
