 I don't know the "best" way to prepare these contacts, but I got
 Schottky contacts on p-type Si by sputtering Titanium on the Si,
 followed by a layer of Aluminum.

 The Si must be clean, of course. After chemical cleaning, I introduced
 the specimen to the ion beam immediately prior to metal deposition
 in order to sputter away any remaining contamination. As I said, I
 don't know if this is the best method, but I did get schottky diodes,
 and I was able to do DLTS measurements with these contacts.
