To aid the interpretation of the EMAS experiments, we perform differential pulse voltammetry (DPV) and electrochemical gating (ECG) measurements on the same colloidal 2H-MoS2 nanosheets. DPV gives insights into the exact position of electronic states within the material, including conduction/valence band and trap states. ECG allows drawing conclusions about the type of states (distinguishes between trap states and band edges) by measuring simultaneously the electrochemical density of states and the conductivity as a function of the applied potential.
