Exciton and light induced ferromagnetism from doping a moiré Mott insulator
Hui Yang, Ya-Hui Zhang
Significant efforts have been dedicated to achieving excitonic insulators. In this paper, we explore a new problem of doping excitons into a Mott insulator instead of a band insula…
Design of High-Quality Reflectors for Vertical Nanowire Lasers on Si
Xing Zhang, Hui Yang, Yunyan Zhang +1
Nanowires (NWs) with a unique one-dimensional structure can monolithically integrate high-quality III-V semiconductors onto Si platform, which is highly promising to build lasers f…
Thermally-driven formation of Ge quantum dots on self-catalysed thin GaAs nanowires
Yunyan Zhang, H. Aruni Fonseka, Hui Yang +5
Embedding quantum dots (QDs) on nanowire (NW) sidewalls allows the integration of multi-layers of QDs into the active region of radial p-i-n junctions to greatly enhance light emis…
Robust Protection of III-V Nanowires in Water Splitting by a Thin Compact TiO Layer
Fan Cui, Yunyan Zhang, H. Aruni Fonseka +14
Narrow-bandgap III-V semiconductor nanowires (NWs) with a suitable band structure and strong light-trapping ability are ideal for high-efficiency low-cost solar water-splitting sys…
Superconductivity in an organometallic compound
Ren-Shu Wang, Liu-Cheng Chen, Hui Yang +6
Organometallic compounds constitute a very large group of substances that contain at least one metal-to-carbon bond in which the carbon is part of an organic group. They have playe…
Highly reproducible superconductivity in potassium-doped triphenylbismuth
Ren-Shu Wang, Jia Cheng, Xiao-Lin Wu +4
Using a new two-step synthesis method - ultrasound treatment and low temperature annealing, we explore superconductivity in potassium-doped triphenylbismuth, which is composed of o…
Absence of structural transition in TM0.5IrTe2 (TM=Mn, Fe, Co, Ni)
J. -Q. Yan, B. Saparov, A. S. Sefat +5
TM-doped IrTe2(TM=Mn, Fe, Co, Ni) compounds were synthesized by solid state reaction. Single crystal x-ray diffraction experiments indicate that part of the doped TM ions (TM=Fe, C…
Origin of the phase transition in IrTe2: structural modulation and local bonding instability
Huibo Cao, Bryan C. Chakoumakos, Xin Chen +7
We used X-ray/neutron diffraction to determine the low temperature (LT) structure of IrTe2. A structural modulation was observed with a wavevector of k =(1/5, 0, 1/5) below Ts?285…
