    摘要： A magnetic field controlled transistor circuit includes a first electrode, a second electrode, and a channel including a magneto-resistive material. The channel is arranged between the first and second electrodes and electrically coupled to the first and second electrodes. The transistor circuit further includes a third electrode, a fourth electrode, and a control layer including an electrically conductive material. The control layer is arranged between the third and fourth electrodes and electrically coupled to the third and fourth electrodes. In addition, an insulating layer including an insulating material is provided. The insulating layer is arranged between the channel and the control layer and configured to electrically insulate the channel from the control layer. A related method for operating a transistor circuit and a corresponding design structure are also provided.

    摘要： 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.

    摘要： 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.

    摘要： A thermoelectric element includes a body formed of a single thermoelectric material and extending in a first direction along which a thermal gradient is established in thermoelectric operation, wherein the body has at least first and second adjacent sections in the first direction; at least one of the sections is subject to stress which is applied to that section substantially all around a central axis of the body in the first direction; and the arrangement is such that the stress results in different strain in the first and second sections producing an energy barrier in the body to enhance thermoelectric operation.
