Abstract
"Cyclotron resonance experiments have been performed on
single crystals of high purity, n-type CdTe at 4.2°K. A reflection
type microwave spectrometer was employed, operating at a frequency
of 70 Gc. The mass and the mobility of the carriers, as determined
from the resonance spectra, identify the carriers as electrons.
The effective mass of electrons in the conduction band of
CdTe was measured to be m 1m = 0.096 + 0.005. This mass value was
p e -
isotropic under rotation of the magnetic field in the (110) plane
of the sample. An excitation spectrum revealed a maximum in the
photosensitivity in the region of the first direct exciton peak.
Changes in the shape of the resonance spectrum as a function
of the intensity and wavelength of the incident illumination ""Tare
recorded."
