Abstract

Wet chemical screening reveals the very high reactivity of Mo(NMe2)4 with H2S for the low-temperature synthesis of MoS2. This observation motivated an investigation of Mo(NMe2)4 as a volatile precursor for the atomic layer deposition (ALD) of MoS2 thin films. Herein we report that Mo(NMe2)4 enables MoS2 film growth at record low temperatures—as low as 60 °C. The as-deposited films are amorphous but can be readily crystallized by annealing. Importantly, the low ALD growth temperature is compatible with photolithographic and lift-off patterning for the straightforward fabrication of diverse device structures.
