The hole carrier field-effect mobility of hybrid molybdenum disulfide (MoS2)\nnanoparticles suspended in poly(3-hexylthiophene) (P3HT) thin film transistor\n(TFT) was found to be enhanced when it compared to P3HT-only TFTs. The\nimprovement in the hole charge transport was found to be a function of the\nconcentration of MoS2 in P3HT with high MoS2 concentrations resulting in an\nincrease in the on-current of the device. Moreover, Au has a high work function\nof 5.1 eV which is suitable with the HOMO level of P3HT. We find that MoS2 and\nAu have the proper energy level for hole transport and injection.\n
