MoS2’s dielectric constant is not constant
Researchers at Harvard University in the US have put forward the first thorough theory of how electric fields affect the dielectric response of molybdenum disulphide – a new, technologically important 2D layered material. Their calculations have revealed that the dielectric constant of MoS2 is not fixed but depends very much on the gate voltage applied to […]
