Abstract
The hole capture cross section /spl sigma//sub p/ of the deep Ti/sup 3+//Ti/sup 4+/ donor level in InP has been measured as a function of temperature. Two different capacitance spectroscopy techniques have been used, namely deep level transient spectroscopy and an isothermal capacitance measurement method for capture measurements at high and low temperatures, respectively. /spl sigma//sub p/ has been found to increase with temperature from 2.8 /spl times/ 10/sup -23/ cm/sup 2/ at 100 K to 2.7 /spl times/ 10/sup -22/ at 300 K, in agreement with a multiphonon emission process. The capture barrier for hole capture amounts to (30/spl plusmn/5) meV.<>
