WebOct 13, 2024 · Moreover, owing to the large work function of the Ti 3 C 2 O 2, it realizes p-type Ohmic contacts with 2D semiconductors. In addition, due to the favorable Ohmic contacts, the on/off ratio of the 5 nm gate-length Zr 3 C 2 (OH) 2 –GeTe FET is around 10 5. WebOhmic Contacts Ohmic contacts do not limit the flow of majority carriers between the two materials. Current is limited by the bulk regions rather than the junction. There are two basic ways in which ohmic contacts can be formed: 1. Choose a system with < with an n-type semiconductor or > 4, with a p-type semiconductor. 2.
WebDec 30, 2024 · p-type Ohmic contacts for both heterostructures are independent of gating up to very large electric field (7 V/nm) suggesting good stability for device applications. … Webproduce a sufficiently ohmic contact by proper choice of the metallic and semiconductor work functions, ~m and ~s (where ~s is the sum of Xs and the energy by which the semiconduc-torts Fermilevel lies belowthe conduction band edge). In those cases where equation I applies, ohmic contacts result when ~m > ~s for a p-type semiconductor and …

Reduction of annealing temperature to prepare low resistance ohmic contact materials for p -type 4H-SiC was achieved by adding Ge to the conventional … WebSep 11, 2024 · 1 Answer Sorted by: 1 Metals are not inherently p-type or n-type as dopants. They are identified as p-type or n-type in a specific material. You cite nickel oxide in your comment. Presumably if a silver atom replaces a Ni atom in the nickel oxide lattice it behaves in a p-type manner.
WebMar 26, 2024 · The graphene/graphene-like germanium carbide interface forms a p-type Schottky contact. The p-type Schottky barrier height decreases as the interlayer distance decreases and finally the contact transforms into a p-type Ohmic contact, suggesting that the Schottky barrier can be effectively tuned by changing the interlayer distance in the …
