Researchers at the Lawrence Berkeley National Laboratory in the US have observed a tunable Bose-Einstein Condensate (BEC) of excitons in an atomically thin semiconductor. A BEC is a coherent quantum state where many particles come together and act as one coherent object. For more than six decades, scientists have been working to generate BECs using excitons or electron-hole pairs. Excitons in ground state Excitons are quasiparticles formed by a bound pair of an excited electron and a positively charged hole. This will aid in the development of fields such as next-generation telecommunications and computing using quantum technologies, as well as exciton-based devices, the press release said.
