We demonstrated a method to grow thickness-precise MoTe2, and further demonstrate that bilayer MoTe2 is a polar metal with strong non-linear Hall effect. When an alternating current is driven in the longitudinal direction of a Hall Bar device of bilayer MoTe2, a transverse Hall voltage at twice the frequency of the current in the longitudinal direction can be detected. This is related to the in-plane Berry curvature dipole, which is allowed in one axis of the crystal and not the orthogonal axis.

Rational Design of Covalent Organic Frameworks as Gas Diffusion Layers
X Li, K Xie, KP Loh et. Al. Angewandte Chemie (In Print) 2023
Non-aqueous Li-air batteries, despite their high energy density and low cost, have not been deployed practically due to their instability in ambient air, where moisture causes parasitic reactions and shortens their life drastically. Here, we demonstrate the rational design of nanoporous covalent organic frameworks (COFs) as effective gas diffusion layers (GDLs). Li-air batteries using COF can cycle under open ambient air (relative humidity up to 95%) and even in various atmospheres with looping oxygen, humid air, and carbon dioxide.
