A team of three engineers and other researchers from the University of California, Riverside (UC-Riverside) recently received a $1.7 million grant from the National Science Foundation (NSF) to research and analyze And to synthesize a new class of ultra-thin film materials to improve the performance of personal electronics, optoelectronic components and energy conversion systems.
The team is led by Alexander Balandin, head of the Department of Electronics and Computer Engineering at the University of California (UC) and head of the Department of Materials Science and Engineering at UCRiverside. Other members include UCRiverside professor Roger Lake, research professor Alexander Khitun, and Georgia University (UGA) assistant professor Tina Salguero.
The goal of this research project is to develop a new type of material called vanderWaals and a heterostructure constructed from this material. This ultra-thin material can consist of only one atomic plane - this is the so-called "two-dimensional" material. The program will delve into new electronic, optical, and thermal phenomena on these materials and heterostructures.
The study is expected to generate new material synthesis technologies that enable ultra-thin film materials to be used in practical applications such as electronic switches, photodetectors, low-power information processing, and direct energy conversion. The novel device implemented with this vanderWaals ultra-thin film material has the potential for high speed and low power consumption.
Researchers will use this prototype with 2D channels
Researchers' interest in 2D materials is mainly motivated by the success of research on the ultimate material such as graphene. Graphene is a monoatomic layer of carbon atoms. Various research activities on graphene have inspired researchers to further observe other interesting new-state physical phenomena and propose more practical applications of graphene, including improving smart phones. Various performances such as tennis racket power supply.
Basically, the conductive and thermal conduction of graphene is different from that of a general three-dimensional material. The Balandin-led UCRiverside research team found that graphene has an extremely high thermal conductivity. The ultra-high thermal conductivity of this 2D material has now found a practical application in thermal management.
Each of the researchers in the National Science Foundation grant team will explore different research and applications of vanderWaals materials.
Balandin will conduct material characterization, fabrication and experimental testing of nanocomponents. Lake will perform the first major theoretical analysis and computer simulation of the properties of this new material and component. Khitun is responsible for designing circuits and systems based on 2D materials and atomic heterostructures. Salguero will chemically synthesize new materials.
