Abstract

, below which the exciton gas behaves as a dilute Bose system, and the Berezinskii-Kosterlitz-Thouless (BKT) superfluid phase becomes accessible. We estimate a maximum BKT transition temperature of ∼143 K in the freestanding limit for the 1s exciton, indicating that monolayer S-GY may provide favorable conditions for high-temperature excitonic superfluidity in graphyne-based materials.
