Patent number: 8106430Abstract: The invented ink-jet printing method for the construction of thin film transistors using all SWNTs on flexible plastic films is a new process. This method is more practical than all of existing printing methods in the construction TFT and RFID tags because SWNTs have superior properties of both electrical and mechanical over organic conducting oligomers and polymers which are often used for TFT. Furthermore, this method can be applied on thin films such as paper and plastic films while silicon based techniques cannot be used on such flexible films. These are superior to the traditional conducting polymers used in printable devices since they need no dopant and they are more stable. They could be used in conjunction with conducting polymers, or as stand-alone inks.Type: GrantFiled: September 14, 2010Date of Patent: January 31, 2012Assignee: William Marsh Rice UniversityInventors: Gyou-Jin Cho, Min Hun Jung, Jared L.

In one method, a self-limiting monolayer technique with an annealing step is used to form shallow junctions. By forming a sulfur monolayer on a surface of an InAs substrate and performing a thermal annealing to drive the sulfur into the InAs substrate, n-type doping for InAs-based devices can be achieved. The monolayer can be formed by surface chemistry reactions or a gas phase deposition of the dopant. In another method, a gas-phase technique with surface diffusion is used to form doped regions. By performing gas-phase surface diffusion of Zn into InAs, p-type doping for InAs-based devices can be achieved.Type: ApplicationFiled: July 26, 2010Publication date: January 26, 2012Applicant: The Regents of the University of CaliforniaInventors: Ali Javey, Alexandra C.

Patent number: 8093684Abstract: The semiconductor of the present invention has iron sulfide and a forbidden band control element contained in the iron sulfide. The forbidden band control element has a property capable of controlling the forbidden band of iron sulfide on the basis of the number density of the forbidden band control element in the iron sulfide. An n-type semiconductor is manufactured by incorporating a group 13 element of the IUPAC system into iron sulfide. Moreover, a p-type semiconductor is manufactured by incorporating a group Ia element into iron sulfide. A semiconductor junction device or a photoelectric converter is manufactured by using the n-type semiconductor and the p-type semiconductor.Type: GrantFiled: January 9, 2007Date of Patent: January 10, 2012Assignee: Sharp Kabushiki KaishaInventors: Yoshiyuki Nasuno, Noriyoshi Kohama, Kazuhito Nishimura

Patent number: 8093589Abstract: In a thin film transistor (1), a gate insulating layer (4) is formed on a gate electrode (3) formed on an insulating substrate (2). Formed on the gate insulating layer (4) is a semiconductor layer (5). Formed on the semiconductor layer (5) are a source electrode (6) and a drain electrode (7). A protective layer (8) covers them, so that the semiconductor layer (5) is blocked from an atmosphere. The semiconductor layer (5) (active layer) is made of, e.g., a semiconductor containing polycrystalline ZnO to which, e.g., a group V element is added. This allows practical use of a semiconductor device which has an active layer made of zinc oxide and which includes an protective layer for blocking the active layer from an atmosphere.Type: GrantFiled: June 14, 2004Date of Patent: January 10, 2012Assignees: Sharp Kabushiki KaishaInventors: Toshinori Sugihara, Hideo Ohno, Masashi Kawasaki

Patent number: 8072043Abstract: A semiconductor component and a method for manufacturing such a semiconductor component which has a resistance behavior which depends heavily on the temperature. This resistance behavior is obtained by a special multi-layer structure of the semiconductor component, one layer being designed in such a way that, for example, multiple p-doped regions are present in an n-doped region, said regions being short-circuited on one side via a metal-plated layer. For example, the semiconductor component may be used for reducing current peaks, by being integrated into a conductor. In the cold state, the semiconductor component has a high resistance which becomes significantly lower when the semiconductor component is heated as a result of the flowing current.Type: GrantFiled: September 12, 2005Date of Patent: December 6, 2011Assignee: Robert Bosch GmbHInventors: Peter Flohrs, Alfred Goerlach, Peter Urbach, Wolfgang Feiler, Ning Qu, Klaus Heyers
