Energy Conversion Devices and Materials (ECO Devices) laboratory develops energy-saving devices, energy-generation devices, and energy-storage devices based on material science. ECO Devices Lab needs active students in the field of energy-saving devices such as LEDs and laser diodes.
ECO Devices Lab is one of the active research groups in the world, which can grow high-quality InGaN layers by metalorganic vapor-phase epitaxy (MOVPE). Our InGaN-based LEDs work from all of the visible region spectra (violet, blue, green, yellow, and red). We are challenging the fabrication of efficient monolithic RYGB LEDs made from InGaN. It will be useful for micro-LED displays and RYGB-LED lightings for the future. These systems are the next generations after OLED displays and lightings with B-LED and phosphor. Also, we will realize new laser diodes, which can cover the missing spectral range of yellow in semiconductor lasers.
As a member of our research lab, students must work hard and are required “some” of the following knowledge in advance.
1. MOVPE 2. Material Science, Physics (ex. Quantum Mechanics, Solid State Physics), and Electrical Engineering 3. Material characterization (PL, Raman, XRD, SEM, TEM, Hall effect) 4. Device fabrication (LEDs, Laser diodes) 5. Device characterization (I-V, I-L, EL spectra)
Applicants should send Statement of Research Purpose at our group (1 page) and CV to
