Binding energy and interatomic spacing
Did you know?
WebIn chemical discussions, the unit of length—atomic sizes, bond lengths (interatomic distances)—has typically been Å (angstroms), where, again by definition, 1 Å equals 10 −8 cm or 10 −10 m because that is the typical interatomic spacing. More recently, length is often written in picometers (pm; 1 Å equals 100 pm). WebTwo-dimensional MX2 (M = Mo, W; X = S, Se, Te) homo- and heterostructures have attracted extensive attention in electronics and optoelectronics due to their unique structures and properties. In this work, the layer-dependent electronic and optical properties have been studied by varying layer thickness and stacking order. Based on the quantum theory of …
