Brown, Frederick C. Mikkor, Mati 2011-05-27T17:57:56Z 2011-05-27T17:57:56Z 10000-01-01 1966 The photocurrents in lightly colored KBr crystals were measured as o function of electric and magnetic fields in the temperature range of 4.2 K to 78 K. The wavelength dependence o£ the photocurrent was determined in the same range of temperature. The symmetry of the conduction band at 4.2 o K was determined from observation of the transverse magnetoconductivity. A new technique of observing cyclotron resonance through electron heating in crystals having high impedance ,and low carrier density was developed. The polaron mass in KBr was measured for the first time using this technique. In addition the static dielectric constant for KBr was determined from 4.2 K to room temperature.
