John,
I have read the reply you have posted to [email protected] on
ohmic contact to Ge.
I have the following additional comment/question on that subject:
Comment: Au on Ge should make Schottky (rectifying-non-ohmic) contact on
moderatly doped Ge. The literature gives the following
Schottky barrier heights (From Sze'book): 0.59 eV on n-type Ge
and 0.30 on p-type Ge.
Question: When you mention the contact you made with Au onto a
single cristal Ge: what was the doping ? Did you observe
any rectifying (diode) effect ?
Thanks
Best regards
Emmanuel Dubois
