High-frequency electroluminescence of TMD heterostructures.

Transferring data from quantum computer processing units to end users is challenging technological problem due to the low energy consumption and high data rate requirements. Due to their unique properties, transitional metal dichalcogenides (TMD) heterostructures are promising candidates for designing cryogenic electro-optical conversion devices, which could be used in such connection. We present the results of our studies of electroluminescence of molybdenum diselenide-tungsten disulfide heterostructures at helium temperatures. The heterostructures have been produces by the exfoliation. The spectrum of electroluminescence is analyzed in a broad range of temperatures and input electric signal frequencies. Our experimental results are supplemented by theoretical modeling of the system. We also discuss application of the obtained results to electrooptical converters to be used in quantum computing data transfer systems.
