The transparent top contact layer of a solar cell is a distributed resistance that cannot be easily represented mathematically. We have used a finite element model to calculate the current distribution in this transparent layer. The calculation gives

Superconducting whiskers grown from BiSrCaCuO powders during a sintering process have been studied as a function of the starting mixture and sintering cycles. Experiments using X-ray diffraction, electron diffraction, EDX, HREM, magnetiza

An experimental determination of the flux distribution in square samples of thin-film superconductors has been conducted by the use of a scanning Hall probe and a magneto-optical thin film. Two 10 mm×10 mm samples, one YBa2Cu3O7 and one TlBaCaCuO, h

This paper addresses the fundamentals of RF switches providing a comparison between semiconductor and RF MEMS switches. The basis of comparison is introduced by defining a figure of merit that is a function of the off-state capacitance and the on-sta

Symposium on Antenna Technology and Applied Electromagnetics [ANTEM 2000].
We are developing a fabrication process for a microelectro-mechanical system (MEMS) microwave switch. Our aim is to make a switch that operates from dc to 40 GHz with low insertion loss and high isolation. The, electrostatically activated, switch is

Symposium on Antenna Technology and Applied Electromagnetics [ANTEM 2000].
We have demonstrated the microwave characteristics of a MEMS switch built on a quartz substrate even though the actuators do not function properly. The results show very broadband performance with insertion loss much less than that available from any

Thin films of MgO with a thickness of 0.1 μm were deposited by reactive rf sputtering on monocrystalline p-type Si substrates as a diffusion barrier for high-Tc superconductor/semiconductor hybrid devices. After a heat treatment at temperatures from
While this work is completely concerned with a semiconductor switch, the origin of the requirement was based on hybrid superconductive/semiconductive electronics. High temperature superconductivity (HTS) allows planar microwave circuits to be built w

The structure of CeO2 films grown on (1102) sapphire and on YBCO thin films was investigated. The films reported on here were grown by pulsed excimer laser deposition and their surface structure was probed using atomic force microscopy. We found that
