Company News >> The UK developer of green gallium nitride microLED successfully raised more than $600,000 29th,Nov,2022

Uk-based Kubos Semiconductors recently closed a $605,000 funding round. The money will help the company push its cubic gallium nitride LED technology into new markets such as AR and VR microLED displays.

The funding came from existing investors, including Turquoise, the UK merchant bank, and its LCIF2 "green technology" fund, as well as individual new investors. This is the company's second round of funding, following a $920,000 Series A round in 2020 led by the LCIF2 fund, which also participated in the latest round.

Proprietary cubic gallium nitride technology greatly improves light output and efficiency

Founded in 2018, Kubos Semiconductors' unique cubic gallium nitride (" cubic GaN ") technology improves the light output and efficiency of green leds. Specifically, they identified the potential of their proprietary material to convert leds at much faster rates than those developed with hexagonal crystal phases and significantly improve the efficiency of green leds.

The image above shows a 25μm(radius) cubic gallium nitride LED with quantum well peaks in the "green gap". The carrier lifetime measured in the cubic gallium nitride quantum well at less than 0.5ns shows that it is more than 20 times faster than the typical C-sided hexagonal gallium nitride LED(≈10ns).

Using a fabless semiconductor model, Kubos Semiconductors' technology is fully compatible with standard LED development processes on large wafers and enables lower volume production costs. Previously, Kubos Semiconductors has demonstrated the first commercially compatible LED based on the gallium nitride cubic crystal phase, promising more efficient solid-state lighting applications and groundbreaking visible light communication (VLC) applications. The company also plans to use the technology to produce red GaN leds in the future.
