A new approach to digital encoding of continuous waveforms employs digital hardware to unite the economy of single-integration delta modulation (AM) with the efficiency of pulse code modulation (PC
The sticking coefficient alpha(E) describes the probability that an incoming charged particle with a low energy E will stick to the surface of the dielectric fluid.
We experimentally determine the density dependence of the transport lifetime (tt) obtained from low field Hall measurements and the quantum lifetime (tq) derived from analysis of the amplitude of S
A four-wave mixer model is presented for which exact analytic results can be obtained in a regime where the usual perturbation procedures no longer apply.
Two dimensional electron gas (2DEG) in a quantum well or an inversion layer, unlike an ordinary grounded metallic plane, does not completely screen an applied transverse electric field.
A high responsivity GaAs/AlGaAs quantum cascade detector is demonstrated at a wavelength of 15 mu m.
Summary form only given.
A quantum cascade (QC) laser with a heterogeneous cascade containing two substacks previously optimized to emit at 5.2 mum and 8.0 mum wavelengths, respectively, is presented.
Quantum cascade (QC) lasers with double metal-semiconductor waveguide resonators are reported for operating wavelengths of 19, 21, and 24 mum.
A quantum-cascade laser using a double-quantum-well graded superlattice as the active region is presented.
