Query: Determination of band offsets of Ga2O3/FTO heterojunction for current
  spreading for high temperature and UV applications   Because of relatively low electron mobility of Ga2O3, it is important to
identify proper current spreading materials. Fluorine-doped SnO2 (FTO) offers
superior properties to those of indium tin oxide (ITO) including higher thermal
stability, larger bandgap, and lower cost. However, the Ga2O3/FTO
heterojunction including the important band offset and the I-V characteristics
have not been reported. In this work, we have grown the Ga2O3/FTO
heterojunction and performed X-ray photoelectron spectroscopy (XPS)
measurement. The conduction and valence band offsets were determined to be 0.11
and 0.42 eV, indicating a minor barrier for electron transport and type-I
characteristics. The subsequent I-V measurement of the Ga2O3/FTO heterojunction
exhibited ohmic behavior. The results of this work manifests excellent
candidacy of FTO for current spreading layers of Ga2O3 devices for high
temperature and UV applications.
