| Abstract: | We have, for the first time, studied photoacoustic absorption spectrum of intrinsic absorp-tion edge of singlecrystalline MoS_2 at room temperature in the wavelength range of 540 to 740nm,and have found A, B two exciton absorption peaks and impurity peak. The experimental re-sults are in good agreement with previous crees obtained from transmission measurements andthe photocurrent spectrum. |
