摘要

研究了在电子-空穴对非共振光激发下，hBN包覆的MoSe单层中激子和三角子的发光与温度和泵浦强度的关系。发光谱线的位移和强度的重新分布可以用自由电子的费米气体和氮化硼中杂质的存在引起的电子局域态的影响来解释。

Luminescence of MoSe2 Monolayers: Effect of Temperature and Pumping

The luminescence of excitons and trions in a MoSe monolayer encapsulated with hBN under nonresonant photoexcitation of electron–hole pairs was studied as a function of temperature and pumping intensity. The shift of luminescence lines and the redistribution of intensities can be explained by the influence of both the Fermi gas of free electrons and localized states of electrons caused by the presence of impurities in boron nitride hBN.
