The application of high-resolution NMR spectroscopy to the structural analysis of copolymers is illustrated by a detailed investigation of the vinylidene fluoride (VF(2)) - tetrafluoroethylene (F
AlGaAs/InGaAs on GaAs substrate is the most commonly used material for QWIPs. Using these compounds, we have already demonstrated focal plane arrays from 4.5 to 15 mu m.
Single-crystalline, lattice-matched (Ca,Sr)F(2) films have been grown by molecular-beam epitaxy on GaAs (100) and (111) As substrates.
This article reviews our present understanding of surface reconstructions on clean silicon.
We have examined a series of samples consisting of 200A In sub x As sub 1-x As layered in a hetero-junction bipolar transistor (HBT) structure (In sub x Ga sub 1-x As on GaAs, followed by GaAs, A1G
High quality single crystal rare earth superlattices of Gd- Y with wavelength varying from 42 to 8 atomic layers were grown by the recently developed metal molecular beam epitaxy technique.
