Abstract

For reliable use of Molybdenum Disulfide (MoS2) FETs in ULSI applications device reliability issues like hysteresis behaviour and non idealities must be well understood and mitigated. In this work, we present unique hysteresis behaviour in the I-V characteristics of few layer MoS2 FETs. Root cause and physics behind the hysteresis behaviour has been explored by repeated experiments under various electrical, temperature, pressure, and environmental conditions. A trap based theory is proposed considering the device behaviour in different conditions and these observations give insight towards device passivation and choosing the right dielectric for reliable utilization of MoS2 FETs.
