We have mapped the temperature and composition dependence of the tetragonal-orthorhombic phase transition temperature, t sub d, in the high-temperature superconductor, La sub (2- x) Sr sub x CuO (
Direct transmission measurements of long wavelength infrared (LWIR) absorption in n-doped GaAs/AlGaAs multi-quantum-well (MQW) structures are made at cryogenic temperatures and under applied bias.
Screening measurements of the temperature-dependent magnetic penetration length lambda of c-axis oriented thin films of YBa sub 2 Cu sub 3 O sub 7 have been made in perpendicular magnetic fields H
We report the temperature (T) and perpendicular magnetic-field (B) dependence of the Hall resistivity rho(xy)(B) of dilute metallic 2D holes in GaAs over a broad range of temperature (0.02-1.25 K).
We have investigated the temperature dependence of the optical absorption in InGaAsP lasers emitting at 1.57micron by measuring the resonant frequency as a function of output power at various tempe
Because of the vacuum used in mass spectrographic evolved gas analysis, the usual effects of temperature lag between actual and apparent sample temperatures are exaggerated.
The etched mesa buried heterostructure (EMBH) distributed feedback lasers fabricated using semi-insulating InP blocking layers have bandwidths in the 12 to 15 GHz range at 20C, 15 mW.
Second harmonic generation (SHG) is reported in Quantum Cascade (QC) lasers with active regions that also support nonlinear cascades with large second order nonlinear susceptibility.
