Disorder-Induced Ordering in Gallium Oxide Polymorphs [PDF]

open access: yesPhysical Review Letters, 2022
Polymorphs are common in nature and can be stabilized by applying external pressure in materials. The pressure/strain can also be induced by the gradually accumulated radiation disorder. However, in semiconductors, the radiation disorder accumulation typically results in the amorphization instead of engaging polymorphism. By studying these phenomena in

Heterostructure formation of group-III sesquioxides via cation-exchange reactions with metal chloride gases

open access: yesAIP Advances, 2023
Thermodynamic analyses and experimental demonstrations were performed to investigate whether cation-exchange reactions (CERs) with metal chloride gases are a feasible technique for forming heterostructures of group-III sesquioxides.

Synthesis and Polymorphism of Mixed Aluminum–Gallium Oxides [PDF]

open access: yesInorganic Chemistry, 2020
The synthesis of a new solid solution of the oxyhydroxide Ga5-xAlxO7(OH) is investigated via solvothermal reaction between gallium acetylacetonate and aluminum isopropoxide in 1,4-butanediol at 240 °C. A limited compositional range of 0 ≤ x ≤ 1.5 is produced, with the hexagonal unit cell parameters refined from powder X-ray diffraction (XRD) showing a ...

Photoluminescence of chromium in gallium oxide and aluminum gallium oxide under pressure

open access: yes, 2023
β-Ga2O3:Cr3+ and AGO were examined under nonhydrostatic conditions by using mineral oil as a pressure-transmitting medium, which is nonhydrostatic above ~2.5 GPa. Similar to the case in ruby, the R1 line is much more sensitive to nonhydrostatic stress than R2.

Electrical and thermal characterisation of liquid metal thin-film Ga $$_2$$ 2 O $$_3$$ 3 –SiO $$_2$$ 2 heterostructures

open access: yesScientific Reports, 2023
Heterostructures of Ga $$_2$$ 2 O $$_3$$ 3 with other materials such as Si, SiC or diamond, are a possible way of addressing the low thermal conductivity and lack of p-type doping of Ga $$_2$$ 2 O $$_3$$ 3 for device applications, as well as of improving

A yeast model of 5‐oxoproline accumulation reveals a general toleration to 5‐oxoproline

open access: yesFEBS Open Bio, EarlyView.
Using a yeast model, we show that even high accumulation of 5‐oxoproline causes only mild cellular stress and does not trigger oxidative stress. Instead, cells adapt by activating efflux pumps and diverse protective pathways, suggesting that previously proposed harmful effects of 5‐oxoproline may arise from indirect metabolic imbalances rather than the
