Ideal ohmic contacts to InP

Contacts to p‐Type InP

“…In-alloy films of 1-3 ~m thickness seem to be optimum for making large-area contacts, since for thicker In layers the problem of mounting due to surface tension becomes critical. Island formation during sintering can be counteracted by covering the InZn film with an overlay of a higher melting point metal; this is a well-known technique for Inalloy or Sn-alloy contacts to n-InP (7,8)…”
