About $26\%$ of the matter in our Universe is made up of Dark Matter (DM),which interacts with Standard Model (SM) matter only through gravitational orweak interactions. Many proposals have been made by scientists about thepossible candidates of DM - WIMPs, axions, ALPs, black holes etc. And range ofits mass could be extremely broad - from Planck scale to as light as $10^{-22}$eV. Experiments to detect DM are extremely challenging, as DM does not exhibitappreciable interactions with ordinary matter. May be due to such elusivenature, so far it has not been possible to detect DM, though many experimentsare going on worldwide to do so. With about 40 orders of magnitude variation intheir mass, it is possible that their gravitational interaction too is veryweak, and many creative proposals have been made to detect possible DMcandidates, with vast variation of techniques and target materials. In thiswork, we propose a new experiment to detect sub-MeV range DM particles, usingthe semiconductor superlattice superstructure (SSS) as the target material.Such materials have band gap of the order of few hundreds of milli eV, and aresuitable for detecting sub-MeV range particles scattering off electrons. Thephotons emitted as a result of excitation of SSS lie in the micrometer rangeand may be detected via quantum cascade lasers (QCL).
