When building with molecules, it is important to understand how they stick to each other. The problem is that the methods used to measure this are themselves an influencing factor on the process. A new study presents a method that excludes this influence.
Scientists have found that it is the intrinsic switching behavior of the graphene electrodes, rather than the properties of the phase change material, that ultimately limits the device scaling and therefore its performance.
This synthesis of hBN in a controlled layer-by-layer fashion is critical to a number of applications, including tunneling barriers, used in transistors for low power devices, atomically thin capacitors, and two-dimensional transistors, which are smaller and use much less power than traditional silicon transistors.
Atom-scale building blocks that have been compared to microscopic Lego are allowing researchers to play with the properties of common materials, and the possibilities are so great that it could keep scientists busy for the next 50 years.
