We study the temperature effects on gain, refractive index, and the linewidth enhancement (or alpha) factor in a 2D semiconductor. We consider both the standard alpha factor due to carrier density variation and that due to temperature variation. The so-called total alpha factor due to both carrier density and temperature is also studied. As a result of temperature change, the alpha factors can be positive, negative, or zero.
