Molecular decoration uncovers molybdenum disulphide grain boundaries

Molybdenum disulphide (MoS2) is a promising candidate for ultrathin electronics and photodetectors because of its unique optical and electronic properties. In such applications, the characterisation of grain boundaries in the sample or device is of utmost importance. Reporting in Nanotechnology, researchers based at Universidade Federal de Minas Gerais (UFMG) develop an easy method for grain boundary detection in MoS2 using a facile self-assembled monolayer (SAM) decoration method.
