Good ohmic contact to n-type indium phosphide (n-InP) with cadmium oxide (CdO), a transparent conducting oxide (TCO), has been achieved. Hydrogen plasma surface pretreatment of the n-InP substrate, prior to the pulsed laser deposition (PLD) of the CdO film, is key to achieving ohmic contact. On substrates pretreated with a hydrogen plasma, contact resistances as low as (6.8 ±2.8) ×10-6 AZAcm2 are obtained.
