The Oscillations of 2D-Electron Density of States in a Transverse Magnetic Fieldyed to study the energy distribution of the density of one-particle electronic states — D(E). The previously employed methods for investigations of 2D-D0S at the Fermi level — dn./dE. were based on the measurements of magnetization,. electron heat capacity,. magnet ocapacitance,. contact potential d

Picosecond Raman and Luminescence Studies of Carrier Relaxation in Quantum Wellsservation of relatively long lived electrons on the second subband of a 215A MQWS. When the well is narrower, so that the n=2 to n=l transition can occur with emission of a longitudinal optic phonon, we find that the lifetime of carriers in the n=2 band is too short to measure with our technique.

Gain Saturation and Features in the Threshold Behavior of AIIIBV Heterostructure Lasersn this and some other Features of the threshold behavior of QW DH lasers the calculations of the dependences of gain and radiative lifetimes on current densities have been performed for devices with different d.. The calculations predict that the dependence of gain on current density has to become s

Single-Frequency Diode Laser with a High Temperature Stability of the Emission Lineransverse and single longitudinal mode output emission was obtained up to 160 mW (Ith = 120 mA) with external differential quantum efficiency η ≃ 32 percent..The advantages of the dielectric-film waveguide DBR are demonstrated. The use of such DBR results in a high degree of sidemode suppression and
