Patent number: 11636247Abstract: Three-dimensional master equation modeling for disordered semiconductor devices is provided. Charge transport is modeled as incoherent hopping between localized molecular states, and recombination is modeled as a nearest-neighbor process where an electron at a first location and a hole at a second location can recombine at either the first location or the second location. Here the first and second locations are any pair of nearest neighbor locations. We have found that this nearest neighbor recombination model performs substantially better than the conventional local recombination model where an electron and a hole must be at the same location to recombine. The recombination rate is modeled as a product of a prefactor ?, hopping rates and state occupancies. Importantly, we have found that sufficient simulation accuracy can be obtained by taking ? to be given by an empirically derived analytic expression.Type: GrantFiled: July 25, 2019Date of Patent: April 25, 2023Assignee: Simbeyond Holding B.V.Inventors: Reinder Coehoorn, Peter Arnold Bobbert, Feilong Liu, Jeroen Cottaar

Patent number: 10573690Abstract: The invention relates to a method for producing a radiation detector used to detect ionizing radiation including a first inorganic-organic halide Perovskite material (24) as a direct converter material and/or as a scintillator material in a detector layer and to a radiation detector comprising a detector layer (24) produced by means of the steps of the method. In order to provide an approach for producing a thick layer (e.g. above 10 ???) of Perovskite material suitable for a radiation detector, it is proposed to grow the material selectively on a seeding layer (23), yielding in a thick polycrystalline layer. One suitable seeding layer (23) to grow lead Perovskite material is made of a bromide Perovskite material.Type: GrantFiled: September 16, 2016Date of Patent: February 25, 2020Assignee: KONINKLIJKE PHILIPS N.V.Inventors: Herbert Lifka, Joanna Maria Elisabeth Baken, Reinder Coehoorn, Paulus Albertus Van Hal, Herfried Karl Wieczorek, Helga Hummel, Cornelis Reinder Ronda, Matthias Simon

Patent number: 7288834Abstract: The semiconductor device has a security coating with embedded magnetic particles and magnetoresistive sensors. This renders possible a measurement of the impedance of security elements defined by magnetoresistive sensors and security coating.

Patent number: 7069568Abstract: A record head for the thermally assisted magnetic recording on a storage medium. The head has an inductive section, which includes a magnetic circuit having a record flux guide ending in a record pole, and an optical section, which includes an optical guide ending in an optical outlet. The optical guide is arranged beside the magnetic circuit and is an optical layer transparent to a selected wavelength. The optical layer is interposed between two cladding layers, of which one is formed by the record flux guide of the magnetic circuit and the other is formed by a layer having an index of refraction smaller than the index of refraction of the optical layer. The record head makes it possible to minimize the time that elapse between the moment of maximal energy absorption in the medium and the moment of recording on the medium in a thermally assisted recording process.Type: GrantFiled: June 14, 2001Date of Patent: June 27, 2006Assignee: Koninklijke Philips Electronics N.V.Inventors: Reinder Coehoorn, Albert Hendrik Jan Immink

Publication number: 20060028748Abstract: An information carrier (10) has an information plane that has a pattern of superparamagnetic material constituting an array of storage locations (11). The presence of a specific superparamagnetic material (12R, 12G, 12B, 12Y) at the information plane represents a value of a storage location. The superparamagnetic materials have a specific response to a varying magnetic field, e.g. a known decay time. A storage unit has an interface surface (32) for cooperating with the information plane, and has coils (27) for generating the varying magnetic field. The interface surface has an array of magnetic sensor elements (24,25,26) each having a sensitive area for generating a read signal. A processing unit (33) detects said presence via the specific response by processing the read signal.Type: ApplicationFiled: October 8, 2003Publication date: February 9, 2006Applicant: Koninklijke Philips Electronics, N.V.Inventor: Reinder Coehoorn
