This British green gallium nitride中不 microLED developer successfully少人 raised over $600,000

Kubos Semiconductors, a UK-ba風紙sed company, recently closed事一 a $605,000 financing round. Th子爸e funding will help the company很音 take its cubic gallium ni請道tride LED technology 廠鐵to new markets such as A線什R and VR microLED displays.

Proprietary cubic gallium nitride 暗木technology to dramatically improve 電坐light output and efficiency

Founded in 2018, Kubos Semico腦道nductors' unique cubic gallium nitr做玩ide ("cubic GaN") technology 歌筆improves the light output and efficien銀答cy of green LEDs. Speci們我fically, they have discovered 自件the potential of their proprietar拍費y material to convert LEDs at a fast他子er rate than that developed 白愛for hexagonal crystal phases an女和d to significantly improve the ef草上ficiency of green LEDs.

T山樂he carrier lifetime in the cubic GaN 學呢quantum well is measured at l男影ess than 0.5ns and is s輛來hown to be more than 20 times fa信電ster than a typical C-sided he子外xagonal GaN LED (≈10ns).

Kubos Semiconductors is using a fabl樹放ess semiconductor model with technolog員嗎y that is fully compatible又志 with standard LED development pr劇對ocesses on large wafe多友rs and enables lower volume production 我理costs. Previously, Kubos Semiconduc多光tors has demonstrated黑都 the first commercially compati路得ble LEDs based on GaN cubic crysta少離l phases, promising more eff物照icient solid-state li時業ghting applications and groundbr冷子eaking visible light communicati我木on (VLC) applications. The compa男舞ny also plans to use this technolo城票gy to produce red GaN LED術白s in the future.

Commenting on the financing火知, Kubos CEO Caroline O 'Brien 來筆said, "We are pleased綠金 to have received continued sup花你port from LCIF2 and other山購 shareholders, and to welcome a number 你兵of new investors that will 見綠help us achieve our te冷微chnical and commercial goals.我空 We are also excited about the prospe可朋ct of developing our own tech志老nology capabilities in new markets,懂生 such as improving t就媽he efficiency of native red micro務呢-LEDs for AR/VR and displays, as well a火個s providing high switc鄉讀hing speed LEDs for visible light comm城北unication applications.&qu吧司ot;

For his part, Turquoise 用歌principal Desmond Astley-市市Cooper commented, "We ar船相e excited to be invol家低ved in the many uses of this e媽如xciting new material technology, includ多請ing the future of small form fact器長or LED devices."
