The New, New Transistor
- adrian_b 3y agoThe research paper: https://www.researchgate.net/publication/376769551_Demonstration_of_AlN-based_Vertical_p-n_Diodes_with_Dopant-free_Distributed_Polarization_Doping https://www.researchgate.net/publication/376769551_Demonstra... This is indeed an extremely important result. The successful demonstration of a new semiconductor material suitable for power electronic devices is a very rare event. During a century of evolution, the semiconductor materials used for power devices have been copper oxide, selenium, germanium, silicon, silicon carbide and gallium nitride. Now it is pretty certain that aluminum nitride will be added to this list. Besides those, a few other materials, mainly gallium arsenide, have been used for very high frequency devices, but at much lower maximum powers than those from this list.
- Smoosh 3y agoExciting and valuable work. Let’s hope it does become commercially viable in the near future.
- mikewarot 3y agoIn an associated article from 2022[1], they talk about transistors that can operate at 500C, which is hot enough to be included in heating element of a soldering iron! Also, these could work on the surface of Venus. [1] https://group.ntt/en/newsrelease/2022/04/22/220422a.html https://group.ntt/en/newsrelease/2022/04/22/220422a.html
