Coulometric determination of arsenic in gallium arsenide crystal wafers
The determination of small variations in the stoichiometry of undoped, semi-insulating gallium arsenide can be achieved by using constant current coulometry. Samples taken from a wafer are etched in HF, dissolved in NaOH-peroxide solution, then treated [...]
InGaN/GaN/AlGaN-based laser diodes grown on free-standing GaN substrates
The InGaN multi-quantum-well (MQW)-structure laser diode (LD) was grown on an epitaxially laterally overgrown GaN on sapphire. The lowest threshold current densities between 1.2 and 2.8 kA cm−2 were obtained when the number of InGaN well layer was [...]
Thermal oxides on the Ga-face of low defect density bulk gallium nitride (GaN) were controllably produced under varying conditions and subsequently analyzed. The thermal oxidation was performed in a dry oxygen atmosphere at different temperatures and different oxidation times. Each oxide layer was identified [...]
