Comparison of solid-state thermionic refrigeration with thermoelectric refrigeration
Journal of Applied Physics, 2001A theoretical analysis of single-barrier thermionic emission cooling in semiconducting materials is performed using Fermi–Dirac statistics. Both maximum cooling and coefficient of performance are evaluated. It is shown that the performance of a thermionic refrigerator is governed by the same materials factor as thermoelectric devices.

Thermal switching requirements for solid state magnetic refrigeration
Journal of Magnetism and Magnetic Materials, 2021Abstract Magnetic refrigeration, based on the magnetocaloric effect, is an attractive alternative to the conventional vapor-compression technology. In a solid state magnetic refrigerator the traditional alternated fluid flow is replaced by two solid thermal switches (TSs) that control the heat flux.

Electrocaloric Materials for Solid‐State Refrigeration
Advanced Materials, 2009AbstractThe electrocaloric effect (ECE) in dielectric materials has great potential in realizing solid‐state cooling devices with compact size and high efficiency, which are highly desirable for a broad range of applications. This paper presents the general considerations for dielectric materials to achieve large ECE and reviews the experimental ...

Solid-state refrigeration for cooling microprocessors
IEEE Transactions on Components and Packaging Technologies, 2006Thin-film thermoelectrics (TECs) are potential candidates for cooling microprocessors due to their large cooling power density and ability to integrate with packages. In addition, there are no moving parts or noise generated during their operation. In particular, thin-film TECs offer the ability to cool localized regions of high heat flux (hot spots ...

Solid-State Optical Refrigeration
2014Abstract The field of optical refrigeration of lanthanide-doped solids emerged in 1994 with the first laser cooling of an Yb 3 + -doped fluoride glass, and it has recently advanced into the cryogenic regime with the demonstration of cooling Yb 3 + -doped fluoride crystals to sub-100 K temperatures.

Light-Emitting Diodes for Solid-State Refrigeration
Light, Energy and the Environment, 2017Electroluminescence, the conversion of electrons into externally emitted photons, is an intrinsic cooling process in a light-emitting diode as long as the applied voltage is less than the photon energy. When the diode is sufficiently efficient so that cooling due to electroluminescence surpasses heating due to internal losses, it becomes a solid-state ...

Thermoelectric module design strategy for solid-state refrigeration
Energy, 2016Abstract In this paper, a new characterization factor for thermoelectric module design in thermoelectric refrigeration is presented with guidelines for practical design strategy. It has been general practice to optimize the geometric factor (G-factor), the ratio of the area to the leg length of a thermoelectric leg, and the number of leg pairs ...
