The ballistic BL-MoS 2-based p- and n-MOSFETs with the tuned stacking arrangement demonstrate an on-state current on the order of 10 3 ♚/µm along with an on-state/off-state current ratio greater than 10 3, a near-ideal (> 65 mV/decade) subthreshold swing, and small (< 30 mV/V) drain-induced barrier lowering effects.īernardi, M., Palummo, M., Grossman, J.C.: Extraordinary sunlight absorption and one nanometer thick photovoltaics using two-dimensional monolayer materials. Indeed, 24.12% and 31.37% improvements in the on-state current and transconductance are observed, respectively, for the p-MOSFET compared with the natural stacking arrangement of BL-MoS 2. The results indicate that the hole effective masses in both the longitudinal (transport) and transverse direction are highly sensitive to the interlayer stacking arrangement, and the performance of the p-MOSFET can be significantly tuned for a suitable stacking configuration of the BL-MoS 2. The corresponding effects on the MOSFET device characteristics are then analyzed. The effect of three different interlayer stacking arrangements of bilayer (BL) molybdenum disulfide (MoS 2) channel material on the device behavior of p- and n-metal–oxide–semiconductor field-effect transistors (MOSFETs) is extensively investigated using first-principles calculation based on density functional theory, emphasizing electronic properties such as the eigenstates, effective mass, band structure, and total energy of the BL-MoS 2 for various stacking arrangements.
