A solid state Pomeranchuk refrigerator

Cryogenics, 2005
Abstract Recently we have shown that YbInCu 4 and related compounds present a solid state Pomeranchuk effect. At their first order volume transition, a local moment phase coexist with a renormalized Fermi liquid in analogy with 3 He at its melting curve. This structural transition can be affected by pressure and magnetic field. We show here that as

Comparison of solid-state thermionic refrigeration with thermoelectric refrigeration

Journal of Applied Physics, 2001
A 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.

Solid-state refrigeration for cooling microprocessors

IEEE Transactions on Components and Packaging Technologies, 2006
Thin-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

2014
Abstract 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.

Low-cost p-type Bi2Te2.7Se0.3 zone-melted thermoelectric materials for solid-state refrigeration

, 2020
Bismuth-telluride-based solid solutions are the unique thermoelectric (TE) materials near room temperature and the commercial ingots are usually grown by zone melting (ZM) method.

High-performance electrocaloric cooling devices for efficient and compact solid-state refrigeration

Thermo-X
The electrocaloric (EC) effect represents the changes of polarization entropy and/or temperature of dielectrics when an external electric field is applied and removed.
