The light-emitting transistor (LET) is examined as a fundamental circuit element for electronic-photonic integration. Basic device properties, methods of integration, and simple electronic-photonic circuits built upon the LET are examined. Novel materials, methods, and devices for heterogeneous integration are also presented.
The heterogeneous integration of compound semiconductors with silicon has been widely studied because of its potential for bringing photonic functionality and improved high-speed performance onto a semiconductor platform with a significant installed manufacturing base. Progress on heterogeneous integration processing methods and devices will be reviewed, and novel methods involving epitaxial transfer...
Uterine fibroids often cause symptoms of pelvic pain, pressure, and bleeding. Traditional therapies have included medical (eg, hormonal therapy) and surgical (eg, myomectomy, hysterectomy) options. Recently, uterine artery embolization was added to the treatment armamentarium. We describe an exciting new noninvasive treatment option using focused ultrasound with magnetic resonance imaging and summarize...
