Carbon Nanotube-Based Lights More Efficient than LEDs

Facebook X LinkedIn Email
SENDAI, Japan, Oct. 15, 2014 — A new carbon nanotube-based light source touts power consumption that is about a hundred times lower than that of an LED. A team from Tohoku University developed the new light source, which uses around 0.1 W for every hour of operation. Carbon nanotubes (CNTs) are poised to replace silicon in making semiconductor materials, they said, and have the potential to meet the ever-increasing demand for greener bulbs and lighting devices. The new device is based on a phosphor screen and single-walled CNTs as electrodes in a diode structure. Specifically, the new device was assembled from...Read full article
