Since optoelectronic devices require electron-hole generation/recombination, it is important to be able to fabricate ambipolar transistors to investigate charge transport both in the conduction band and in the valence band. Although n-type transistor operation for single-layer and few-layer MoS2 with gold source and drain contacts was recently demonstrated, transport in the valence band has been elusive for solid-state devices. Here we show that a multi-layer MoS2 channel can be hole-doped by palladium contacts, yielding MoS2 p-type transistors. When two different materials are used for the source and drain contacts, for example hole-doping Pd and electron-doping Au, the Schottky junctions formed at the MoS2 contacts produce a clear photovoltaic effect.Submitted by Santiago Fabio (fabio.ssantiago@hotmail.com) on 2013-11-26T19:44:38Z No. of bitstreams: 1 222222r.pdf: 799527 bytes, checksum: ac6f6abf24223955440f7105925d65b0 (MD5)Approved for entry into archive by LIVIA FREITAS (livia.freitas@ufba.br) on 2013-11-27T12:53:19Z (GMT) No. of bitstreams: 1 222222r.pdf: 799527 bytes, checksum: ac6f6abf24223955440f7105925d65b0 (MD5)Made available in DSpace on 2013-11-27T12:53:20Z (GMT).
