- 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.
