    Abstract

    In project S4,we will investigate the fundamental physicalproperties of novelsolution-grown ultrathin two-dimensional (2D) semiconductors and their verticaland lateral heterostructures by advanced optical spectroscopy. The physicalproperties to be determined include the crystallinestructure and the vibrational, electronic, and optical properties of the 2D semiconductors. In addition, we willexplore the effect of substrate and interfaceinduced strain and the role of defects and grain boundaries on the physical properties. Our studies willenable us and our ChemPrint partners to control thin-film growth via in-situ monitoring ofspectroscopic signals, to understand lateral andvertical heterostructure formation, and to pattern 2D semiconductors via patterned surface functionalization.

    We will focus on transition-metal dichalcogenides (TMDCs) MoS2, HfS2 and onSnS(e)2 ,on the V-VI semiconductors Sb2S3,Sb2Se3 ,and on patterned 2D semiconductors.
