Electrically driven amplified spontaneous emission (ASE) in a high–current-density LED with an integrated Bragg-reflection waveguide—an important milestone toward a colloidal QD laser diode.
Our device-oriented research exploits the unique properties, versatility, and tunability of colloidal quantum dots to realize new classes of solution-processed devices. These efforts target applications spanning light emission, energy conversion, electronics, optoelectronics, photochemistry, and emerging quantum technologies. Current focus areas include:
Quantum dot lasers, laser diodes, and LEDs
Photocathodes and electron emitters for photochemical applications
Single–quantum-dot light sources for quantum optics
Luminescent solar concentrators and photovoltaic devices
Photodetectors, including ultrafast Auston-switch platforms
