UCLA creates the first stable all-solid-state thermal transistor 1

UCLA (University of California, Los Angeles) recently announced the successful creation of the first stable INA103KU all-solid-state thermal transistor. This breakthrough is expected to bring significant advancements to the field of thermal management, providing more efficient heat dissipation solutions for electronic devices.

The thermoelectric transistor is a crucial technology for controlling the temperature of electronic devices. It achieves heat dissipation by transferring heat from the heat source to a heat sink, thereby maintaining a stable operating temperature for electronic devices. Currently, common cooling methods on the market primarily include fans and liquid cooling, but these methods suffer from issues such as high noise levels, susceptibility to damage, and high energy consumption. In contrast, the thermoelectric transistor can regulate thermal conductivity through electrical current, enabling noiseless, damage-resistant, and energy-efficient cooling performance, making it highly noteworthy.transistor.

However, since thermal transistors need to operate in high-temperature environments, current thermal transistor. are prone to failure under high temperatures. This limits their widespread application in practical scenarios. To address this issue, a research team at UCLA adopted a fully solid-state design, constructing thermal transistors using high-melting-point silicon materials and metal oxides.
