A team of researchers led by Professor Yong-Young Noh and Dr. Youjin Reo from POSTECH has developed a groundbreaking technology using thermal evaporation to create powerful semiconductor layers.
They focused on tin-based perovskite material for high-performance p-type transistors and used lead chloride to improve the quality of thin films.
The newly developed p-type transistors showed impressive performance, with high speed and low power consumption, comparable to commercial n-type semiconductors.
This innovation allows for more stable devices, large-area circuits, and can lead to ultra-thin, flexible screens for smartphones and TVs at low processing temperatures.
