Patent number: 10234176Abstract: A heat pump system includes a structure, in turn including a solid-state phase change material. The solid-state phase change material has a first phase state and a second phase state dependent on the temperature. A heat source is configured to supply heat to a first area of the structure, thereby creating a first domain having the first phase state and thereby storing latent heat in the first domain. The first domain is separated by domain walls from second domains having the second phase state. A heat sink is configured to receive heat from a second area of the structure. Furthermore, an electrical energy supply is configured to supply an electrical current to the structure, thereby moving the first domain and the corresponding latent heat stored in the first domain along the structure from the first area to the second area. A related thermal computing device, a related method, and a related computer program product are also disclosed.Type: GrantFiled: August 18, 2016Date of Patent: March 19, 2019Assignee: International Business Machines CorporationInventors: Bernd W.

Patent number: 9977050Abstract: A method and a scanning probe microscope (SPM) for scanning a surface of a material. The method and SPM have a cantilever sensor configured to exhibit both a first spring behavior and a second, stiffer spring behavior. While operating the SPM in contact mode, the sensor is scanned on the material surface and a first spring behavior of the sensor (e.g. a fundamental mode of flexure thereof) is excited by deflection of the sensor by the material surface. Also while operating the SPM in contact mode, excitation means are used to excite a second spring behavior of the sensor at a resonance frequency thereof (e.g. one or more higher-order resonant modes) of the cantilever sensor to modulate an interaction of the sensor and the material surface and thereby reduce the wearing of the material surface.Type: GrantFiled: November 5, 2010Date of Patent: May 22, 2018Assignee: SWISSLITHO AGInventors: Urs T.

Patent number: 9891112Abstract: A radiation detector and method and computer program product for detecting radiation. The detector comprises a waveguide structure, a sensing structure comprising a phase change material, an optical transmitter and optical receiver. The optical transmitter transmits an optical sensing signal for receipt at the optical receiver via the waveguide structure. The phase change material comprises a first phase state at a first temperature range and a second phase state at a second temperature range and transitions from the first phase state to the second phase state under exposure of the radiation. The sensing structure is arranged in an evanescent field area of the waveguide structure and provides for an evanescent field of the optical sensing signal a first complex refractive index in the first phase state and a second complex refractive index in the second phase state. The first complex refractive index is different from the second complex refractive index.Type: GrantFiled: October 19, 2016Date of Patent: February 13, 2018Assignee: International Business Machines CorporationInventors: Stefan Abel, Lukas Czornomaz, Jean Fompeyrine, Bernd w.

Patent number: 9714863Abstract: An optical spectrometer contains a photodiode and a straining mechanism for imposing adjustable strain on the photodiode. The spectrometer includes a measurement apparatus for measuring variation of photocurrent with strain at different values of the adjustable strain imposed by the straining mechanism. Adjusting the strain allows adjustment of the band gap Eg of the photosensitive region of the photodiode, and this determines the cut-off energy for absorption of photons. Measuring variation of photocurrent with strain at different values of the adjustable strain imposed by the straining mechanism allows study of photons within a desired energy range of the band gap energy corresponding to each strain value.Type: GrantFiled: November 8, 2013Date of Patent: July 25, 2017Assignee: International Business Machines CorporationInventors: Bernd W.
