In this article, we present an experimental study of the impact of the write current wave form on high frequency magnetic recording. It has been found that, at high recording frequencies, current overshoot reduces transition broadening, overwrite deg

This work presents the results of a study using ventricular electrogram signals to identify the heart's evoked response following an electrical stimulus from a pacing electrode. Acute data were collected in vivo from seven human subjects and analyzed

Computation of the equilibrium electrostatic potential and energy band diagram of semiconductor devices with nonuniform composition is considered. We first establish the relationship between the electrostatic potential and the energy band edges and t

A closed-form expression for the current-voltage characteristics of isotype heterojunctions is developed. Unlike previous treatments of this problem which considered only thermionic emission, this theory, in analogy to metal-semiconductor theory, inc

The improvement of solar cell performance through the use of semiconductor heterostructures is an area of current interest. One particular application involves the use of a graded bandgap structure to achieve an increase in the open-circuit voltage V

A numerical method for analyzing heterostructure semiconductor devices is described. The macroscopic semiconductor equations for materials with position-dependent dielectric constant, bandgap, and densities-of-states are first cast into a form identi

A modified version of a recently proposed cost model for millimeter and microwave integrated circuits is applied to the cost analysis of optoelectronic integrated circuits. The particular example that is examined is a four-function receiver module fo

Current-voltage and initial RF measurements are presented on a double-heterojunction HEMT (high-electron-mobility transistor) structure designed for power MMIC applications. The device structure is grown by molecular-beam epitaxy and uses a spatially
