Oxygen-deficiency-driven phase segregation enables enhanced hole transport in amorphous tellurium oxides

Rafael Costa-Amaral, Yu Kumagai

Amorphous oxide semiconductors allow scalable electronics, yet high-mobility p-type counterparts remain rare because O- $2 p$ valence bands are typically deep and spatially localized…

Investigation of Hole Dopability in Oxygen $2 p$ -Dominated Bands

Thi Ngoc Huyen Vu, Yu Kumagai

The development of $p$ -type oxide semiconductors remains impeded by the inherently low-lying valence-band maximum (VBM) dominated by O-2 $p$ states. A prevailing approach to mitigat…
