P. Marie et M. Levalois, HOLE TRAPS PRODUCED BY SWIFT HEAVY-ION IRRADIATION IN P-TYPE GERMANIUM, Journal of applied physics, 75(3), 1994, pp. 1852-1854
Lightly doped, p-type germanium has been irradiated at room temperatur
e with swift heavy ions. Several hole traps, detected by means of deep
level transient spectroscopy, have energies determined to be E(V)+0.2
2, E(V)+0.41, and EV+0.33 eV. The results are compared with those prev
iously obtained for n-type germanium, and the defects are the same in
the two kinds of materials: Divacancies and vacancies-impurity complex
es.
