  • Molybdenum disulphide (MoS2) was irradiated by 0.97 GeV 209Bi ions with the fluence of 1×1010 to 1×1012 ions/cm2. The irradiation effect on the thermal conductivity of MoS2 was analyzed by atomic force microscope (AFM) and Raman spectroscopy. The experimental results show that hillock-like latent tracks are observed on irradiated MoS2 by AFM. The measurement of MoS2 by Raman spectrometer with high laser power results in the increase of local temperature of MoS2, which cause the downshift of peaks position and broadening of E1/2g and A1g peak. Furthermore, according to Raman spectra measured at different laser power, thermal conductivity of MoS2 before and after irradiation was calculated, which show that the thermal conductivity of MoS2 decreases with increasing fluence, from 563 to 132 W/mK for pristine and 1×1012 ions/cm2 irradiated MoS2, respectively.

The irradiation effect on the thermal conductivity of MoS2 was analyzed by atomic force microscope (AFM) and Raman spectroscopy. The experimental results show that hillock-like latent tracks are observed on irradiated MoS2 by AFM. The measurement of MoS2 by Raman spectrometer with high laser power results in the increase of local temperature of MoS2, which cause the downshift of peaks position and broadening of E1/2g and A1g peak. Furthermore, according to Raman spectra measured at different laser power, thermal conductivity of MoS2 before and after irradiation was calculated, which show that the thermal conductivity of MoS2 decreases with increasing fluence, from 563 to 132 W/mK for pristine and 1×1012 ions/cm2 irradiated MoS2, respectively.
