Alzheimer's disease (AD), also known as geriatric dementia, is the most serious dementia occurred among the elders whose age is over 65. Cognitive functions or memory will decay with age and are irreversible. The cause of dementia remains a mystery and the dementia population normally increases within aged societies. It is not only hard to diagnose whether an elderly will suffer from dementia but...
In this letter, we report the high-temperature stability of a lasing wavelength in GaAsSb/GaAs quantum-well (QW) lasers grown by metal-organic vapor phase epitaxy. To the best of our knowledge, this is the first successful use of triethylgallium (TEGa) as the precursor to grow GaAsSb/GaAs QW at low temperature (525degC). The lasing wavelength ranges from 1117 to 1144 nm and varies with temperature...
