- Le brevet est pour la technologie inventée par le défunt Dr Praveen Chaudhari, un récipiendaire de l'U.S. Medal of Technology and Innovation et il couvre la technologie pour un large éventail d'applications électroniques, dont notamment les cellules solaires à couche mince, les diodes électroluminescentes (LED), les transistors en couches minces (TFT), les transistors à effet de champ (FET), les onduleurs solaires et les dispositifs à nanofils.

BRIARCLIFF MANOR, New York, 23 avril 2015 /PRNewswire/ -- Solar-Tectic LLC(« ST ») a annoncé aujourd'hui que l'United States Patent and Trademark Office (USPTO) a délivré un brevet majeur (plus de 50 revendications) pour un large éventail de technologies, dont notamment la croissance de couches semiconductrices monocristallines, fortement texturées ou à grains grossiers sur des substrats peu coûteux, tels que le verre ordinaire.  Les technologies ont été inventées par le défunt Dr Praveen Chaudhari, lauréat de l'U.S. Medal of Technology en 1995, et elles ont des applications dans diverses industries telles que le solaire, les affichages et les LED.

Le brevet américain (12/774 465), intitulé « Methods of Growing Heteroepitaxial Single Crystal or Large Grained Semiconductor Films and Devices Thereon (Méthodes de croissance des couches semiconductrices monocristallines hétéroépitaxiales ou à grains grossiers et les dispositifs à ce sujet) », révèle une technique de croissance modifiée à couche mince (TF) de vapeur-liquide-solide (VLS) qui permet pour la première fois un dépôt à basse température de couches semiconductrices d'une qualité exceptionnellement élevée provenant d'une variété de matériaux, tels que le silicium, le germanium et le GaN (Nitrure de Gallium), sur des substrats peu coûteux.

Le processus de croissance rentable de type nanofils, mais à couche mince, impliquant des alliages eutectiques, est très bien adapté pour des applications industrielles à grande échelle et qui peut être effectué à l'aide de processus de dépôts communs actuellement utilisés dans diverses industries, tels que par faisceau d'électrons (e-beam), par dépôt chimique en phase vapeur (CVD), etc.  

Pour des renseignements généraux ou pour la concession de licence de la technologie, veuillez contacter Carter Ledyard & Milburn LLP  ([email protected]), +1-212-238-8850.

À propos de Solar-Tectic LLC (« ST ») :  Solar-Tectic LLC est un spécialiste de couches minces principalement axé sur le développement des technologies brevetées des couches semiconductrices monocristallines ou fortement texturées sur des rubans métalliques ou de verre.  La société possède un vaste portefeuille de technologies et de propriété intellectuelle à cette fin, toutes fondées sur les inventions par le défunt Dr Praveen Chaudhari, scientifique des matériaux et lauréat de l'US National Medal of Technology and Innovation (1995). Au cours de l'année écoulée, plusieurs articles ont été publiés rendant compte des progrès en matière de R&D, dont notamment « Highly textured silicon [111] crystalline thin-film on buffered soda-lime glass by e-beam evaporation (Couche mince de silicium [111] cristallin fortement texturé sur verre sodocalcique tamponné par évaporation par faisceau d'électrons) » de S. McMahon et coll. et « Crystalline Al203 on buffered soda-lime glass by e-beam (Cristallin Al203 sur verre sodocalcique tamponné par faisceau d'électrons) » de A Chaudhari et coll.
