Abstract

This paper reports on the study of inverted metal-oxide semiconductor (MOS) structures formed through mechanical exfoliation of MoS₂ flakes onto Al₂O₃ or SiO₂ layers grown on degenerately doped p type silicon substrates. Using Au/Ni metal top contacts, multi-frequency capacitance and conductance characterisation were performed to investigate electrically active defects in the MoS₂/oxide structures. This data has been paired with physics-based ac simulations which indicate close to ideal interfacial properties.
