Controlled oxygen vacancy induced p-type conductivity in HfO{2-x} thin films
Erwin Hildebrandt, Jose Kurian, Mathis M. Müller +3
We have synthesized highly oxygen deficient HfO thin films by controlled oxygen engineering using reactive molecular beam epitaxy. Above a threshold value of oxygen vacanci…
Field emission from single and few-layer graphene flakes
S. Santandrea, F. Giubileo, V. Grossi +5
We report the observation and characterization of field emission current from individual single- and few-layer graphene flakes laid on a flat SiO2/Si substrate. Measurements were p…
Charge transfer and trapping as origin of a double dip in the transfer characteristics of graphene based field-effect transistors
Antonio Di Bartolomeo, Filippo Giubileo, Salvatore Santandrea +4
We discuss the origin of an additional dip other than the charge neutrality point observed in transfer characteristics of graphene-based field-effect transistors. The double-dip is…
