The temperature dependence of interlayer excitons in semiconductor heterostructures has garnered significant research interest, particularly in transition metal dichalcogenides (TMDs) like MoS₂ and WSe₂. These materials are favored due to their pronounced excitonic effects and their potential for tunable electronic properties. Material Systems and Temperature Effects: Research predominantly focuses on TMD heterostructures, such as MoSe₂/WSe₂, due to their robust excitonic behavior and strong absorption characteristics [3][6]. These heterostructures allow investigation into phenomena such as exciton formation, relaxation, and transport under varying temperatures [1][5]. Generally, an increase in temperature leads to a decrease in exciton binding energy, attributed to enhanced lattice vibrations that weaken the Coulombic interaction between electrons and holes [5]. Photoluminescence and Dynamics: Photoluminescence (PL) studies are crucial for understanding the temperature-dependent behav
