For MoStransistors fabricated on crested substrates, we observed an almost two orders of magnitude increase in carrier mobility compared to standard devices, as well as very high saturation currents. The mechanical strain in TMDs has been predicted to boost carrier mobility, and has been shown to ...
The International Roadmap for Devices and Systems (IRDS) forecasts that, for silicon-based metal–oxide–semiconductor (MOS) field-effect transistors (FETs), the scaling of the gate length will stop at 12 nm and the ultimate supply voltage will not de
Field-effect transistors based on two-dimensional (2D) materials have the potential to be used in very large-scale integration (VLSI) technology, but whether they can be used at the front end of line or at the back end of line through monolithic or heterogeneous integration remains to be det...
Here we review the promise and current status of 2D transistors, and emphasize that widely used device parameters (such as carrier mobility and contact resistance) could be frequently misestimated or misinterpreted, and may not be the most reliable performance metrics for benchmarking 2D transistors....
(BP) have been developed and demonstrated exceptional performance in fields such as transistors, sensors, biomedicine, catalysts, and photovoltaic cells [41,42,43,44,45]. The first application of 2D materials in PSCs can be traced back to 2013 when H.J. Snaith and colleagues enhanced the ...
The thiophene oligomer α-hexathienylene (α-6T) has been successfully used as the active semiconducting material in thin-film transistors. Field-induced conductivity in thin-film transistors with α-6T active layers occurs only near the interfacial plane, whereas the residual conductivity caused by...
The scaling of silicon metal–oxide–semiconductor field-effect transistors has followed Moore’s law for decades, but the physical thinning of silicon at sub-ten-nanometre technology nodes introduces issues such as leakage currents1. Two-dimensional (2D) layered semiconductors, with an atomic thicknes...
Here we demonstrate (1) wafer-scale and monolithic two-tier 3D integration based on MoS2 with more than 10,000 field-effect transistors (FETs) in each tier; (2) three-tier 3D integration based on both MoS2 and WSe2 with about 500 FETs in each tier; and (3) two-tier 3D integration ...
The recognition of bloody footwear impressions at a crime scene is not an uncommon occurrence for the criminalist. Traditionally these impressions have been recorded by photography or videography either before and/or after chemical enhancement. Photography is an ideal method to begin with since it is...
As a new member in two-dimensional materials family, transition metal carbides (TMCs) have many excellent properties, such as chemical stability, in-plane
