The bandgap dependence on the number of atomic layers of some families of 2D materials can be exploited to engineer and use lateral heterostructures (LHs) as high-performance Field-Eﬀect Transistors (FET). This option can provide very good lattice matching as well as high heterointerface quality. More importantly, this bandgap modulation with layer stacking can give rise to steep transitions in the density of states (DOS) of the 2D material, that can eventually be used to achieve sub-60 mV/decade subthreshold swing in LH-FETs thanks to an energy-ﬁltering source. We have observed this eﬀect in the case of a PdS LH-FET due to the particular density of states of its bilayer conﬁguration. Our results are based on ab initio and multiscale materials and device modeling, and incite the exploration of the 2D-material design space in order to ﬁnd more abrupt DOS transitions and better suitable candidates.

Electrical devices that are composed of semiconductor material, with at least three connections to an external electronic circuit. They are used to amplify electrical signals, detect signals, or as switches.
An effect usually, but not necessarily, beneficial that is attributable to an expectation that the regimen will have an effect, i.e., the effect is due to the power of suggestion.
A multi- and interdisciplinary field concerned with improving health and achieving equity in health for all people. It transcends national boundaries, promotes cooperation and collaboration within and beyond health science fields, and combines population-based disease prevention with individually-based patient care.
A technique of measuring the dielectric properties of materials, which vary over a range of frequencies depending on the physical properties of the material. The technique involves measuring, over a range of frequencies, ELECTRICAL IMPEDANCE and phase shift of an electric field as it passes through the material.
