NS Nanotech Reports World-Record Performance of Red NanoLED
Gallium-nitride nanoLEDs measuring less than a micron in diameter (left) can be tuned to emit various wavelengths of light (right).
Submicron-scale light-emitting diode (LED) is efficient enough for commercial microdisplay applications
The light emitting diode is based on patented technology enabling fabrication of components that will be smaller and draw far less power than current LED solutions, while emitting brighter, more saturated, more stable, and more directional light. NS Nanotech, which has exclusive licenses to LED technologies developed by Prof. Mi’s research teams, is working to enable commercial manufacturing of the nanoLEDs.
The results of the demonstration and description of methods used to grow red-emitting gallium nitride (GaN) nanowire crystals were published by Professor Mi’s team in Applied Physics Letters.
NanoLEDs capable of disrupting AR/VR microdisplay market
“Our nanoLED performance breakthroughs have the potential to disrupt important emerging markets, especially for augmented reality and virtual reality headset displays,” said Dr. Seth Coe-Sullivan, CEO and co-founder of NS Nanotech. “AR/VR eyeglasses will require easily manufactured high-performance nanoLEDs that are orders of magnitude smaller than current LEDs, and we are on a straightforward development path to get there over the next several years.”
Based on exclusively licensed patent portfolios from McGill University and the University of Michigan, NS Nanotech’s technology introduces new methods for growing nanoLEDs and their resulting structures. The company intends to bring costs below the threshold required for integration of nanoLEDs into microdisplays and countless other end products, with breakthroughs in cost and efficiency delivering performance equivalent to chips that today are ten times the size or more.
In addition to red nanoLEDs, NS Nanotech has demonstrated how its technologies have the potential to close the “green gap” in efficiency that currently limits the effectiveness of green LEDs for many applications. In an article published in Nanoletters, Prof. Mi’s group described successful fabrication of a submicron-scale green nanoLED with EQE greater than 25%, a new world record.
UVC nanoLEDs for disinfection of Covid-19 and other pathogens
NS Nanotech’s nanoLED technology also has the potential to deliver invisible ultraviolet-spectrum UVC light that has been proven effective in water and air purification and sterilization of medical equipment. By delivering UVC LEDs featuring the same breakthroughs in cost and performance that it delivers for multicolor microdisplays, the company will be positioned to enable new classes of antiviral and anti-microbial purification solutions.
“UVC light effectively deactivates numerous pathogens, including those causing viral airborne diseases such as Covid-19 and influenza,” Coe-Sullivan said. “Building low-cost, high-performance UVC light emitters into the world’s public and private buildings, transportation systems, schools, homes, and other infrastructure where people gather will have the potential to dramatically reduce or avoid future epidemics and pandemics.”
