Abstract
The evolution of transport properties along a chlorine-doped CdTe crystal grown by the gradient freeze (GF) method has been investigated by time of flight (TOF) measurement. Drift mobilities as high as 1100 cm2/(Vs) and 80 cm2/(Vs) for electrons and holes, respectively, are measured at the initial part of the grown crystal, and were found to decrease with increasing solidified fraction (g). On the other hand, the specific resistivity increases with increasing g. These behaviors can be understood as the dopant (Cl) concentration variation due to segregation during growth. The change in γ-detection properties between crystals having different g is demonstrated.
