South Korean scientists claimed Tuesday to have developed a new semiconductor element which is operable in extreme temperatures such as below 90 degrees Celsius.
The National Research Foundation of Korea said that a research team involving Sungkyunkwan University professor Park Jin-hong and KAIST professor Kim Yong-hoon have successfully developed the second-dimensional semiconductor element which is able to conduct electric charges in extremely low temperatures.
The research team stacked tungsten diselenide (WSe2) vertically to create an electronic device onto a piece of graphene. Graphene is a honeycombed two-dimensional sheet as thin as an atom made up of carbon atoms. It is also known as the "material of dreams" in the semiconductor industry due to its strong and tough efficiency in conducting electricity.
Normally in two-dimensional electronic devices, the electric current is reduced under low temperatures but the researchers found that the electric current was even increased on their grapheme-based WSe2 structure at minus 90 degrees Celsius.
"With this development of the semiconductor element which is operable at extremely low temperatures, a further research can be conducted on the development of switching elements in electric appliances such as cell phones and TVs," professor Park said.
