READ ALSO: Nanomaterials May Help Achieve More Efficient Next Solid-State Computing Generation How Does the Nano-exciton Transistor Works?Ī similar article by Wevolver reports that monolayer semiconductors or transistors are a group of metamaterials that have been studied in the past, and it shows great potential for use in optical computers and other optical information processing technologies, such as controllers and communications. Furthermore, this study is expected to pave the way for the development of exciton-based devices for next-generation electronics and quantum information technology. The team's approach has significant advantages, as a nano-excitonic transistor that uses light can process massive amounts of data at the speed of light while minimizing heat energy loss, the Brighter Side reports. The method is reversible and minimizes physical damage to the semiconductor material. In their study, titled " Nanocavity-Integrated van der Waals Heterobilayers for Nano-excitonic Transistor" published in ACS Nano, the researchers reported that they have developed a new approach using photonic nanocavities and a spatial light modulator to remotely control the density and luminance efficiency of excitons based on polarized light. The researchers had previously proposed technology for controlling excitons using a nano-scale tip to press semiconductor materials, but it was challenging to achieve control due to the limitations mentioned earlier. However, due to the non-homogeneity of semiconductor heterostructures and the poor luminous efficiency of interlayer excitons, as well as the diffraction restrictions of light, controlling intra- and interlayer excitons in nano-scale regions has proven difficult. The construction of a two-bit exciton transistor is enabled by selective management of these two signals. In a semiconductor hetero-bilayer, there are two types of excitons, intralayer excitons, and interlayer excitons, with different optical signals. reported that a team of researchers from POSTECH and ITMO University used intralayer and interlayer excitons in semiconductors to develop a nano-excitonic transistor that can overcome the limitations of existing transistors.Įxcitons are essential to the development of light-emitting elements and a light source for quantum information technology.
