Vertical Charge Carrier Mobility in Organic Thin Films: Studying the Influence of the Substrate in the Case of Benzoquinone on Ag(111)
Fabio Calcinelli, Institute of Solid State Physics

The properties of a material depend on its structure, and no theoretical prediction of the most stable thin film structures through traditional, exhaustive first-principle studies is feasible due to the combinatorial explosion in the number of possible polymorphs. For monolaye ... more
