Ionic gate spectroscopy of 2D semiconductors

Nature Reviews Physics. 2021;

Reliable and precise measurements of the relative energy of band edges in 2D semiconductors are needed to determine band gaps and band offsets, as well as to establish the band diagram of devices and heterostructures. However, commonly employed techniques such as optical studies and scanning…

Magnetization dependent tunneling conductance of ferromagnetic barriers

Nature communications. 2021;12(1):6659

Recent experiments on van der Waals antiferromagnets have shown that measuring the temperature ( T ) and magnetic field ( H ) dependence of the conductance allows their magnetic phase diagram to be mapped. Similarly, experiments on ferromagnetic CrBr 3 barriers enabled the Curie temperature to be…

Theory of cross quantum capacitance

Physical Review Research. 2021;3(4):043036

Impressive progress in the control of atomically thin crystals is now enabling the realization of gated structures in which two electrodes are separated by atomic scale distances. The electrical capacitance of these structures is determined by phenomena that are not relevant in capacitors with…
