Summary: Polymers that extend covalently in two dimensions have attracted recent attention as a means of combining the mechanical strength and in-plane energy conduction of conventional two-dimensional (2D) materials with the low densities, synthetic processability and organic composition of their one-dimensional counterparts. Here we demonstrate a homogenous 2D irreversible polycondensation that results in a covalently bonded 2D polymeric material that is chemically stable and highly processable. Further processing yields highly oriented, free-standing films that have a 2D elastic modulus and yield strength of 12.7 +/- 3.8 gigapascals and 488 +/- 57 megapascals, respectively. This synthetic route provides opportunities for 2D materials in applications ranging from composite structures to barrier coating materials.

Summary: The discovery of graphene has led to the investigation of various 2D carbon allotropes, including penta-graphene (PG), through computational simulations. This study focused on examining the electronic, structural, dielectric, piezoelectric, and catalytic properties of one- and two-dimensional PG-like structures (P-XC2 where X = C, Si, or Ge). The results showed that P-XC2 systems have an indirect band gap energy ranging from 2.65 to 3.55 eV. P-GeC2 exhibited the highest dielectric and piezoelectric constants, while penta-graphene had higher elastic constants compared to P-SiC2 and P-GeC2. Additionally, the band alignment suggested that PXC2 and their respective nanotubes could be favorable for hydrogen production through water splitting.

Theoretical calculations show that the free-standing BGe monolayer is highly stable and maintains its metallic feature even after absorbing different numbers of Na atoms, making it a potential candidate for reversible Na-ion battery anode materials with desirable performance. The calculated migration energy barrier, open-circuit voltage, and theoretical specific capacity of the BGe monolayer are also superior to those of some other two-dimensional materials.

Summary: The deviation of the Schottky barrier (SB) in the ultraclean van der Waals contact between 2D MoS2 and 3D In from the Schottky-Mott limit (SML) is investigated. The deviation is found to be attributed to the combined effects of interface potential difference (?V) and Fermi-level shift (?E-F). By coating a thin film of Au, Sc, or Ti on the back side of In, the deviation and the sum of ?V and ?E-F can be reduced. Particularly, the SB is significantly reduced to 0.12 eV in the Ti coating case. This interface engineering can be applied to regulate the SB between a 2D semiconductor and a 3D alloy.

Summary: The Schottky barrier (SB) in the van der Waals contact between MoS2 and indium deviates from the Schottky-Mott limit (SML). The deviation is attributed to the combined effects of interface potential difference (Delta V) and Fermi-level shift (Delta EF). Coating a thin film of Au, Sc, or Ti on the back side of indium can mitigate the SB deviation and decrease Delta V and Delta EF. Notably, the Ti coating reduces the SB to 0.12 eV, smaller than the value in the Au coating case.
