Gap and Van Hove Measurements via Low-loss Electron Energy Loss Spectroscopy on Atomically thin MoxW(1-x)S2 Nanoflakes
Pelaez Fernández, Mario (Universidad de Zaragoza, Instituto de Nanociencia de Aragón, Spain) ; Suenaga, Kazu (Nanotube Research Center, National Institute of Advanced Industrial Science and Technology, Japan) ; Arenal, Raul (Institute of Nanosciences of Aragon, Spain)Abstract:
Band gap tailoring of 2D materials has been of interest for the past years. Using low-loss electron energy loss spectroscopy (EELS), in a scanning transmission electron microscope (STEM), it has been confirmed, following previous experimental (photoluminescence) and theoretical (DFT) studies, that the band gap of atomically thin nanoflakes of MoxW(1-x)S2 does shift with the alloying degree of the sample
