Publication number: 20130193401Abstract: A memory array including a plurality of memory cells. Each word line is electrically coupled to a set of memory cells, a gate contact and a pair of dielectric pillars positioned parallel to the word line. Dielectric pillars are placed on both sides of the gate contact. Also a method to prevent a gate contact from electrically connecting to a source contact for a plurality of memory cells on a substrate. The method includes formation of a pair of pillars made of an insulating material over the substrate, depositing an electrically conductive gate material between and over the pillars, etching the gate material such that it both partially fills a space between the pair of pillars and forms a word line for the memory cells, and depositing a gate contact between the dielectric pillars such that the gate contact is in electrical contact with the gate material.Type: ApplicationFiled: February 1, 2012Publication date: August 1, 2013Applicant: International Business Machines CorporationInventors: Matthew J.

Publication number: 20130193404Abstract: An infrared photoconversion device comprising a collector with at least an active layer made of a single sheet of doped single-layer, bilayer, or multilayer graphene patterned as nanodisks or nanoribbons. The single sheet of doped graphene presents high absorbance and thus, the efficiency of devices such as photovoltaic cells, photodetectors, and light emission devices can be improved by using graphene as the central absorbing or emitting element. These devices become tunable because their peak absorption or emission wavelength is changed via electrostatic doping of the graphene.Type: ApplicationFiled: January 26, 2012Publication date: August 1, 2013Applicants: CONSEJO SUPERIOR DE INVESTIGACIONES CIENTIFICAS, FUNDACIO INSTITUT DE CIENCIES FOTONIQUESInventors: Frank KOPPENS, Francisco Javier García De Abajo
