A clever trilayer assembly strategy for 2D materials

Abstract

Recently in Matter, Hu et al. developed a trilayer structure composed of 2D materials, intermediate layer, and substrate, which enabled decoupling of the mono-mode instabilities and designable deterministic mode toward self-assembly of atomically thin 2D materials. The strategy is universal for different 2D materials and induces anisotropic piezoresistive and mechanical-optoelectrical coupling effects, being utilized for fabrication of highly sensitive and ultra-fast responsive mechanical sensors.

The deterministic self-assemblies endow unique properties distinct from those of their parent 2D materials, such as anisotropic piezoresistive effects. Benefited from the properties induced by deterministic self-assemblies, we report a concept of deterministically self-assembled micro/nano-electronics of 2D materials, such as 3D anisotropic tactile sensors.
