PG - 28130-28135 LID - 10.1021/acsami.6b07271 [doi] AB - Deposition of high-k dielectrics on two-dimensional MoS(2) is an important process for successful application of the transition-metal dichalcogenides in electronic devices. Here, we show the effect of H(2)O reactant exposure on monolayer (1L) MoS(2) during atomic layer deposition (ALD) of Al(2)O(3). The results showed that the ALD-Al(2)O(3) caused degradation of the performance of 1L MoS(2) field effect transistors (FETs) owing to the formation of Mo-O bonding and trapping of H(2)O molecules at the Al(2)O(3)/MoS(2) interface. Furthermore, we demonstrated that reduced duration of exposure to H(2)O reactant and postdeposition annealing were essential to the enhancement of the performance of top-gated 1L MoS(2) FETs. The mobility and on/off current ratios were increased by factors of approximately 40 and 10(3), respectively, with reduced duration of exposure to H(2)O reactant and with postdeposition annealing.
