The transport of carriers in superlattice minibands forms the basis of many exciting new concepts (Esaki and Tsu [1]).

We describe a technique for measuring chemical shift anisotropy (CSA) lineshapes in NMR spectra of polycrystalline or amorphous solids.

Thermoelectric modules (TEMs) are solid-state devices used for cooling, heating and power generation.

From measurements of absorption and phase shift of microwaves passing through a discharge, several wavelengths long, in a waveguide the electron densities and collision frequencies may be deduced i

Recent advances in the interpretation of optical emission spectra from plasmas have made it possible to measure parameters such as electron temperature (T-g), relative electron density, and gas tem

X-ray sensitivity ("Cliff-Lorimer" k-) factors have been determined for a limited number of elements including oxygen, on an ultra- thin window (UTW) Si(Li) energy dispersive X-ray detector interf

A new technique is described through which the refractive index and extinction coefficient of an isotropic solid can be determined using measurements of normal incidence reflectance and pseudo- Bre
