Researchers show how MXenes' rich chemistry can be used to create doping-free 2D transistors with intrinsically low resistive contacts while maintaining balance mode operation. With a suitable functional termination, MXenes can become a semiconductor or a metal with a different work function. The researchers exploit this unique property of MXene to propose a Schottky barrier transistor, which can be implemented with a bare MXene by converting it to a semiconductor in the channel region ...
