Abstract: Hybrid heterostructures, made of organic molecules adsorbed on two-dimensional metal monochalcogenide,generally unveil interfacial effects that improve the electronic properties of the single constitutive layers. Here,we investigate the interfacial electronic characteristics of the F4-TCNQ/single-layer GaSe heterostructure. Asharp F4-TCNQ/GaSe interface has been obtained and characterized by x-ray photoemission spectroscopy. Wedemonstrate that a high electron transfer from 1TL GaSe into the adsorbed F4-TCNQ molecules takes place,thereby yieldin... (read more)

Topic-specific impact indicators

Popularity:
This indicator reflects the "current" impact/attention (the "hype") of an article in the research community at large, based on the underlying citation network.
Influence:
This indicator reflects the overall/total impact of an article in the research community at large, based on the underlying citation network (diachronically).
Citation Count:
This is an alternative to the "Influence" indicator, which also reflects the overall/total impact of an article in the research community at large, based on the underlying citation network (diachronically).
Impulse:
This indicator reflects the initial momentum of an article directly after its publication, based on the underlying citation network.
