Abstract
A new n-Ge Ohmic contact scheme is demonstrated using a three stage deposition of Ni, Ge and Ni. The lowest specific contact resistivity demonstrated was (1.68 ± 0.4) x 10-7 Ω-cm2, with a low transfer length of (0.95 0.12) for deposited Ni and Ge annealed at 340 oC for 30 s on n-Ge with a doping density of 3 x 1019 cm -3. © The Electrochemical Society.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione
