The study published in Nature Communications focuses on the development of amorphous boron nitride (aBN) thin films for enhancing the performance of two-dimensional (2D) electronic devices. Researchers employed atomic layer deposition (ALD) at low temperatures (below 250°C) to create uniform aBN layers, addressing the challenge of integrating dielectrics with 2D materials like MoS2. The aBN films exhibited high oxidative stability and a dielectric strength of 8.2 MV/cm, which is crucial for improving the electronic properties of 2D semiconductors. The study highlights the advantages of aBN over traditional hexagonal boron nitride (hBN), particularly in terms of scalability and processing temperature. The researchers successfully fabricated aBN/MoS2 quantum well structures and double-gated monolayer MoS2 transistors, demonstrating the potential of aBN as a dielectric material that can significantly enhance the performance of 2D electronic devices. This work paves the way for the practical application of 2D materials in next-generation electronics by providing a reliable method for dielectric integration.
