Luminescent excitation spectra were measured for the F and M centers in KCl; in particular, for the F band, M band, and the M2 transition. In all 3 cases, the spectra were nearly double-Gaussian in shape, and the efficiency ...

Silicon crystals which have been irradiated with neutrons, high energy electrons, or gamma-rays at room temperature show two strong luminescence bands in the near infrared. Both bands have a sharp zero-phonon line followed ...

The influence of uniaxial stress upon three types of imperfections occurring in the alkali halide crystal lattice has been investigated. The imperfections are the interstitial atom, the interstitial ion, and the negative ...

Tunneling in boron doped p-type silicon metal-semiconductor and metal-insulator-semiconductor tunnel junctions has been studied at low temperatures by measuring the derivatives, di/dV and d2i/dV2, of the current-voltage ...
