A comparative study of charge trapping effect in p-type MoTe2 and WSe2 FETs using pulsed current–voltage measurements

Abstract: P-type semiconductors are indispensable for achieving complementary metal oxide semiconductor and integrated circuits based on two-dimensional (2D) semiconductors, and tungsten diselenide (WSe2) and molybdenum ditelluride (MoTe2) are the promising channel materials for PMOS. In this work, we report on the charge trapping effects on hysteretic behavior and field-effect mobility (μ FE) of the p-type WSe2 and MoTe2 FETs using fast pulsed current–voltage (I–V) measurements. The hysteresis is redu… Show more

“…We calculated the depletion width of the p‐WSe 2 /n‐Ge heterojunction via xp =2Ndε1ε2VbiqNaε1Na+ε2Nd, and xn =2Naε1ε2VbiqNdε1Na+ε2Nd where ε 1 , ε 2 are the dielectric constants of WSe 2 and Ge respectively; N d is the doping concentration of n‐Ge; and N a is the doping concentration of p‐WSe 2 calculated from the fabricated WSe 2 FET. [ 31,32 ] N d of n‐Ge (LD) and n‐Ge (HD) was ≈2.0 × 10 16 cm –3 and ≈8.0 × 10 19 cm –3 , respectively, which was obtained by Hall measurements. N a was calculated to be 8.0 × 10 17 cm –3 .…”
