UCLA creates the first stable all-solid-state thermal transistor 2

The research team first used chemical vapor deposition technology to grow thin films on silicon substrates. Then, they used ion implantation technology to form a silicon matrix in the silicon thin film. Next, the research team grew metal oxide thin films on a silicon substrate as a key component of thermal transistors. Finally, they used photolithography and dry etching techniques to form the structure of the thermal transistor.

This all solid state design enables the thermal transistor to operate stably in high temperature environments and has the characteristics of high thermal conductivity and low resistance. The research team conducted a series of tests on this new type of thermal transistor, and the results showed that its performance at high temperatures is excellent. Compared to traditional thermal transistors, this all solid state thermal transistor has higher heat dissipation efficiency and longer service life. transistor
