Loops are the facilities between the local central office and the subscriber. For the most part, the individual customer's loop is a pair of metallic conductors.
The experiments by the author and L. H. Germer, by G. P. Thomson and by others from which the wave properties of electrons are adduced are briefly described.
The production of integrated circuits involves some of the most sophisticated and precise manufacturing techniques ever developed.
The linear and quadratic electrooptic coefficients in narrow single and strongly coupled GaAs-AlxGa1-xAs quantum wells have been measured, The quadratic electrooptic effect is enhanced over that of
Tin alloys such as Sn-0.7% Cu and Sn-2% Bi were identified as viable alternatives to tin-lead finishes.
An analytical solution for the metal resistance-controlled plating current distribution on circular wafers is obtained to determine the conditions under which a uniform metal film can be electro-de
Electro-reflectance spectroscopy of Ge(x)Si(1-x) decoupled multiple quantum-well structures grown by MBE has been used to yield confinement energy and strain shifts for the E(0)) and E(1) optical
We report the first absolute measurement of electric-field- induced changes in refractive index in InGaAs quantum well heterostructures.
We have measured electric-induced-changes in refractive index in GaAs- and InP-based quantum well heterostructures.
