Abstract :
Bi doped and Bi and Yb codoped CdTe crystals
grown by the Bridgman method have been characterized by
cathodoluminescence (CL) in the scanning electron
microscope. CL images show a dense network of highly
decorated grain boundaries in the Bi doped samples and
dopant striations in the codoped crystals, attributed to the
presence of Yb. Bi contributes to the appearance of the A
luminescence band at 1.43 eV. The influence of Yb dopant
on the CL spectra is discussed
