Epitaxial Growth and Air‐Stability of Monolayer Antimonene on PdTe₂

Abstract

Monolayer antimonene is fabricated on PdTe by an epitaxial method. Monolayer antimonene is theoretically predicted to have a large bandgap for nanoelectronic devices. Air-exposure experiments indicate amazing chemical stability, which is great for device fabrication. A method to fabricate high-quality monolayer antimonene with several great properties for novel electronic and optoelectronic applications is provided.

Antimonene/bismuthene vertical Van-der Waals heterostructure: A computational study

“…Therefore, no chemical covalent bonds exist between the layers and other mechanisms like Van-der Waals's interactions or orbitals hybridization may connect the layers. The lack of localization and the absence of covalent bonds between the layers are also reported in the previous heterostructures like G/Sb, PdTe 2 /Sb [28,44] as well as Antimonene grown on (111) Ag substrate [45].…”

Two-Dimensional Antimony Oxide

“…Antimony is one of these elements and can form layered structures called antimonene. Recently, few-layer antimonene was realized experimentally by different methods such as epitaxial growth [9][10][11] or exfoliation. [12][13][14][15] Additionally, the electronic and vibrational properties of monolayer antimonene have been investigated theoretically, with a predicted band gap of about 2.4 eV.…”

Noncovalent Functionalization and Charge Transfer in Antimonene

“…[24] Recently,v an der Waals and molecular beam epitaxy (MBE) have been applied for the synthesis of antimonene on different surfaces,t hereby exhibiting good stabilities and high electrical conductivities of up to 10 4 Sm À1 in about 30 nm thick flakes. [25,26] Despite synthetic efforts,t he chemistry and therefore the molecular doping of antimonene remains completely unexplored. In relation to that, we have recently reported on the noncovalent functionalization of BP with electron-poor and polarizable polycyclic aromatic molecules, thus observing ar emarkable charge-transfer behavior, and improving the resistance of the flakes against oxygen degradation.…”
