“…Today, the primary interest in these compounds is due to the discovery of monolayers of TX 2 . Technologies for assembling van der Waals heterostructures have led to the creation semiconductor nanodevices based on individual monolayers of TX 2 : nanoscale field effect transistors [1][2][3][4], low-dimensional rectifying contacts [5], phototransistor devices [6], spin-valley filters [7], battery applications [8,9], and photoluminescence effects [10,11].…”
