(Universiti Malaysia Perlis, 2009)
The design of optoelectronic devices fabricated from III-Nitride materials is aided by knowledge of refractive index and absorption coefficient of these materials .The optical properties of Al0.11Ga0.89N, Al0.03Ga0.97N, ...
Thermal aging study at 150 °C and 200 °C: Gold ball bonds to aluminum bond pad
(The Electrochemical Society, 2009-03-17)
This paper presents the study of the thermal aging of the gold ball bonds and aluminum bond pad at 150 °C and 200 °C for various interval times. Process decapsulation and Field Emission Scanning Electron Microscopy (FESEM) ...
Nano-silver microcavity enhanced UV GaN light emitter
(Inderscience Enterprises Limited, 2009)
We report results of measurements that help to clarify the role of silver in the reflection of UV emission light from GaN. A GaN as an active layer was sandwiched between two silver metal reflectors. GaN layer on sapphire ...
