Fermi-level pinning factor
WebHowever, the C 2 N–Ni, –Pt, –V 2 C, –Mo 2 C, –graphene contact systems form n-type Schottky contacts in either the armchair or zigzag direction owing to the relatively strong Fermi level pinning (the pinning factor S = 0.32 in the armchair direction and S = 0.26 in the zigzag direction). WebThe current understanding is that MIGS are the dominant factor leading to Fermi level pinning at metal semiconductor interfaces in the vicinity of the charge neutrality level E CNL of the...

WebMar 9, 2024 · Weaker Fermi level pinning (FLP) at the Schottky barriers of 2D semiconductors is electrically desirable as this would allow a minimizing of contact … WebThe Fermi level pinning factor S is defined as the value of the fitted slope. Furthermore, the schematic band structures of CrX 2 N 4 based FETs with different metal electrodes are determined based on the electronic structure and QTS results.
WebPolarity control of MoS 2 is realized without extrinsic doping by employing a Fermi‐level‐pinning‐free 1D metal contact design. The use of high‐work‐function metals such as Pd and Au gives rise to high‐performance p‐type MoS 2 with hole mobility exceeding 400 cm 2 V −1 s −1 at 300 K. WebOct 31, 2024 · In 2D FETs, Fermi-level pinning is attributed to the high-energy metal deposition process, which would damage the lattice of atomically thin 2D semiconductors and induce the pinning of the metal …
