Researchers from Moscow and New Orleans develop new material for electronics
7 Sep '16
Scientists at MISiS, a leading Moscow-based tech university, and their colleagues from the Tulane University of Louisiana, U.S., have created what they claim is the world’s first single-crystal semiconductor material with huge potential for use in microelectronics, Geektimes.ru reported.
The discovery was made possible through the use of micromechanical exfoliation, the method once used to discover graphene. The experimenters utilized a combination of tantalum, palladium/platinum and selenium, a synthetic material which was put together more than 30 years ago but had hardly ever been used until now.
Researchers from the Nonorganic Nanomaterials laboratory at MISiS were responsible for the theoretical part of the project; they were led by Dr. Pavel Sorokin. Experiments were mostly conducted at the Tulane University of Louisiana; the head of the team is Prof. Jiang Wei. The results of this unique research have been published in English in Nano Letters.
It’s not the first time scientists faced the task of developing a single-crystal semiconductor. Putting together such a material for use primarily in optoelectronics and microelectronics is expected to help boost capacity and lower the energy consumption of a great range of devices. Reducing a material to nanodimensions often gives it extraordinary electronic, optical, mechanical, chemical and biological properties, the researchers pointed out.
