Study on eye movement characteristics and intervention of basketball shooting skill [PDF]

open access: yesPeerJ, 2022
Background The shooting aiming point is very important in basketball because it may affect the field goal percentage (FG%). The purpose of this study was to explore the influence of shooting aiming point practice on FG% and to search for new training ...

A systematic study on the efficacy of low-temperature GaN regrown on p-GaN to suppress Mg out-diffusion

open access: yesFrontiers in Materials, 2023
Embedding p-type gallium nitride (p-GaN) in AlxGa1-xN-based thin films has garnered significant interest as a versatile structure for bandgap engineering such as tunnel/super-junctions or current blocking/guiding functions in electronic devices. However,

Biological diversity and conservation of forest ecosystems in Kyrgyzstan [PDF]

open access: yesСибирский лесной журнал, 2016
Kyrgyzstan is a natural repository of genetic resources and the diversity of species and natural laboratory, where at the small area are represented almost all altitudinal belts, ranging from semi-desert, ending with glacial-nival belt.

The results of introduction of Scots pine Pinus sylvestris L. in Northen Kyrgyzstan [PDF]

open access: yesСибирский лесной журнал, 2017
The forests of Northern Kyrgyzstan are distinguished by poor species composition. Severe forest growing conditions, dry climate, vertical zoning, exposition of forests to the northern slopes, while the opposite slopes are treeless created a more or less ...

Zirconium Mediated Hydrogen Outdiffusion From p-GaN [PDF]

open access: yesMRS Internet Journal of Nitride Semiconductor Research, 1999
We have shown that Zr-based metallization can effectively remove hydrogen from the p-type GaN subsurface, which eventually leads to the formation of an ohmic contact. As the release of hydrogen starts at ∼900°C, the thermal stability of the contact system is of particular importance.

The Structural and Optical Investigation of Grown GaN Film on Porous Silicon Substrate Prepared by PLD [PDF]

open access: yesEngineering and Technology Journal, 2023
The optical properties of a grown gallium nitride (GaN) thin film on a porous silicon (P-Si) substrate was investigated. A Photo-electrochemical etching method was used to synthesize the Psi substrate, and a physical deposition method (pulsed laser ...

Formation of ultra-high-resistance Au/Ti/p-GaN junctions and the applications in AlGaN/GaN HEMTs

open access: yesAIP Advances, 2021
We report a dramatic current reduction, or a resistance increase, by a few orders of magnitude of two common-anode Au/Ti/p-GaN Schottky junctions annealed within a certain annealing condition window (600–700 °C, 1–4 min).
