Monolayer graphene can be magnetized by coupling to an antiferromagnetic thin film of chromium selenide, resulting in an exchange splitting energy as high as 134 meV at 2 K.
The two-dimensional semiconductor Bi2O2Se can be oxidized to create an atomically thin layer of Bi2SeO5 that can be used as the insulator in scaled field-effect transistors.
A van der Waals ferroelectric tunnel junction with asymmetric metal and graphene contacts exhibits a high resistance ratio between on and off states, and could be of value in the development of low-power computing.
An atomically thin high-κ gate dielectric of Bi2SeO5 can be formed via layer-by-layer oxidization of an underlying two-dimensional semiconductor, allowing high-performance field-effect transistors and inverters to be fabricated.
Hydrogen-resist lithography with the tip of a scanning tunnelling microscope can create p-type dopant nanowires and p–n junctions by using diborane as a p-type dopant precursor.
Broadband electrostatic force microscopy can be used to non-destructively image n-type and p-type dopant layers in silicon devices with a lateral resolution of 10 nm and a vertical resolution of 0.5 nm.
Neuromorphic engineering aims to create computing hardware that mimics biological nervous systems, and it is expected to play a key role in the next era of hardware development. Carver Mead recounts how it all began.
Neuromorphic engineering attempts to create brain-like computing hardware and has helped reawaken interest in computer chip start-ups. But is the technology ready for mainstream application?
This Review Article examines the development of neuro-inspired computing chips and their key benchmarking metrics, providing a co-design tool chain and proposing a roadmap for future large-scale chips.
Monolayers of boron nitride can be used to build high-performance radio-frequency switches that can operate at the frequencies required for 5G and the communication systems beyond it.
