Nuclear-Magnetic-Resonance Studies of the Semiconductor-to-Metal Transition in Chlorine-Doped Cadmium Sulfide

Metal-insulator transition in a doped semiconductor

Millikelvin measurements of the conductivity as a function of donor density and uniaxial stress in bulk samples of phosphorus-doped silicon establish that the transition from metal to insulator is continuous, but sharper than predicted by scaling theories of localization. The divergence of the dielectric susceptibility as the transition is approached from below also points out problems in curre...

NUCLEAR MAGNETIC RESONANCE STUDY OF THE STRUCTURE OF GLYOXALDIHYDRAZONE

Study of the nuclear magnetic resonance spectra of glyoxaldihydrazone in dimethylsulfoxide and deuterochlorofonn leads to the conclusion that this compound exists predominantly in non-chelate structure

Magnetic Polarons and the Metal-Semiconductor Transition in (Eu,La)B6 and EuO: Raman Scattering Studies

We present inelastic light scattering measurements of EuO and Eu1−xLaxB6 (x=0, 0.005, 0.01, 0.03 and 0.05) as functions of doping, magnetic field and temperature. Our results reveal a variety of distinct regimes as a function of decreasing T: (a) a paramagnetic semimetal regime, which is characterized by a decrease in Γ, the carrier scattering rate, with decreasing temperature and a loss of spe...
