In a nanoscopic system defined by a limited number of charges, the combined dynamics of bound and free charges become important. Here we present a model system based on the electrostatic interaction between a metallic tip of a scanning tunnelling microscope and a GaAs(110) semiconductor surface. The system is driven out of equilibrium by optical excitation, which provides ambipolar free charge carriers, and by an optically induced unipolar tunnel current. This combination enables the active control of the density and spatial distribution of free and bound charge in the space-charge region, that is, modifying the screening processes. Temporal fluctuations of single dopants are modified, meaning we are able to control the noise of the system. It is found that free charge carriers suppress the noise level in field-controlled, nanoscopic systems."],["dc.description.sponsorship","[CRC1073]; [C4]"],["dc.identifier.doi","10.1038/ncomms10108"],["dc.identifier.isi","000369018600001"],["dc.identifier.pmid","26728867"],["dc.identifier.purl","https://resolver.sub.uni-goettingen.de/purl?gs-1/12893"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/42049"],["dc.notes.intern","Merged from goescholar"],["dc.notes.status","zu prüfen"],["dc.notes.submitter","Najko"],["dc.relation","SFB 1073: Kontrolle von Energiewandlung auf atomaren Skalen"],["dc.relation","SFB 1073 | Topical Area C | C04 Untersuchung und Kontrolle photochemischer Reaktionen durch lokale optische Anregung im Rastertunnelmikroskop"],["dc.relation.issn","2041-1723"],["dc.relation.orgunit","Fakultät für Physik"],["dc.rights","CC BY 4.0"],["dc.title","Controlling the screening process of a nanoscaled space charge region by minority carriers"],["dc.type","journal_article"],["dc.type.internalPublication","yes"],["dc.type.peerReviewed","yes"],["dc.type.subtype","original_ja"],["dc.type.version","published_version"],["dspace.entity.type","Publication"]]
