Abstract

Few-layer MoS ₂ prepared by the chemical vapor deposition method is deposited on SiO ₂ samples with/without sulfide treatment in order to experimentally study the mechanism of conduction-type conversion in MoS ₂ . The MoS ₂ thin film deposited on a SiO ₂ substrate with sulfide treatment shows n-type behavior, whereas the MoS ₂ thin film deposited on a SiO ₂ substrate without sulfide treatment exhibits p-type behavior. Experimental identification confirms that n-type conversion is due to a combined effect of the broken Si[Formula presented]O bonds and the formation of Si[Formula presented]S bonds at the SiO ₂ surface that results in the removal of oxygen dangling bonds and a change in the MoS ₂ [Formula presented]SiO ₂ interaction.
