A Process for the Recovery of Gallium from Gallium Arsenide Scrap
, 2019 The recovery of gallium (Ga) from gallium arsenide (GaAs) scrap using a leaching-ion exchange method was investigated. The ground GaAs scrap was leached, using 2.0 N nitric acid at 30 °C for 1.0 h, and the dissolution of Ga and arsenic (As) reached 98 ...

The Restructuring of Aluminum on Gallium Arsenide [PDF]
IEEE Transactions on Components, Hybrids, and Manufacturing Technology, 1978 The restructuring of aluminum (Al) on GaAs has been observed on low-power GaAs field-effect transfers (FETs) and on special test structures. For 4 X 104heating and cooling cycles, temperature swings as low as 90°C produced restructuring. Restructuring is weakly dependent on deposition temperature, and no change in the Al resistance was observed.

Metamaterial-Enhanced Nonlinear Terahertz Spectroscopy
EPJ Web of Conferences, 2013 We demonstrate large nonlinear terahertz responses in the gaps of metamaterial split ring resonators in several materials and use nonlinear THz transmission and THz-pump/THz-probe spectroscopy to study the nonlinear responses and dynamics.

Advanced Functional Materials, EarlyView.This review synthesizes the evolution of radiative heat transfer, emphasizing the transition from far‐field to near‐field regimes. Traditional frameworks, such as Planck's law, are revisited alongside modern innovations like fluctuational electrodynamics. Applications span nanoscale thermal management, energy harvesting, and thermophotovoltaic systems.

Valence band engineering of GaAsBi for low noise avalanche photodiodes
Nature Communications, 2021 An avalanche photodiode is an opto-electronic amplifier that uses impact ionization to provide enhanced sensitivity at the expense of excess noise. In this manuscript, the authors demonstrate that a small amount of Bismuth (Bi) in Gallium Arsenide (GaAs)
