Article Synopsis
- The field of twistronics focuses on the electronic structures of twisted atomically thin layers, but achieving consistent layer alignment and single crystalline quality is a current challenge.
- A new approach proposes using nanocrystalline two-dimensional (2D) films on three-dimensional (3D) substrates to create properties that depend on the twist between layers.
- The study demonstrates that growing hexagonal boron nitride (h-BN) thin films on silicon carbide substrates leads to unique optical and thermal properties, making it a promising strategy for practical applications in nanotechnology.
Heteroatom Functionalization of H-Terminated Diamond Surfaces.
ACS Appl Mater Interfaces
August 2023
Diamond surface functionalization has received significant research interest recently. Specifically, H-termination has been widely adopted because it endows the diamond surface with negative electron affinity and the hole carrier is injected in the presence of surface transfer dopants. Exploring different functional groups' attachment on diamond surfaces and their impact on the electronic structure, using wet and dry chemical approaches, would hence be of interest in engineering diamond as a semiconductor.

The phase stability regimes of these BN phases are still under debate, and phase transformations of h-BN/c-BN remain a topic of interest. Here, we investigate the phase stability of 2D/3D h-BN/c-BN nanocomposites and show that the coexistence of two phases can lead to strong nonlinear optical properties and low thermal conductivity at room temperature.
