Hall effect measurements are important in determining the electronic properties of emerging semiconductor materials, but care must be taken in their use and analysis.

Atomic-layer yttrium doping can be used to form ohmic contacts between molybdenum disulfide channel layers and metals, creating high-performance 2D transistors with low contact resistances.

Conductive organic fibres can be tethered to biological surfaces without impeding biological features.

Graphene plasmon polaritons are expected to enable rapid data transfer and processing; however, these plasmons are difficult to access. Terahertz electronics now facilitate the efficient generation, manipulation and on-chip detection of wave packets lasting as little as 1.2 ps. This advance could lead to the development of nanoscale terahertz circuits.

This Perspective explores the potential of organic electrochemical neurons, which are based on organic electrochemical transistors, in the development of adaptable and biointegrable neuromorphic event-based sensing applications.

Terahertz electronics that can create and control ultrashort graphene plasmon wave packets with durations as short as 1.2 ps can offer on-chip handling of plasmonic signals.

A yttrium-doped metallic two-dimensional buffer layer can be used to improve charge carrier transport between the metal contacts and semiconductor channel in molybdenum-disulfide-based transistors.

An optimized pulsed voltage write–verify switching approach can be used to improve the switching performance of memristors based on hexagonal boron nitride for radiofrequency circuit applications.

By separating high- and low-temperature fabrication processes, cantilevers that incorporate sensing electronics between a soft polymer core and hard ceramic layers can be made, providing high force sensitivity and robustness to harsh environments.

A membrane of polymer fibres containing semi-embedded liquid metal particles can be selectively ruptured with a patterned stamp to produce stretchable circuits with high resolution and interfacial adhesion between the liquid metal and the polymer.

With the help of an orbital spinning technique, substrate-free open networks of imperceptible fibres can be created on a range of biological surfaces, providing on-skin sensors that can record electrocardiogram signals, skin-gated organic electrochemical transistors, and augmented touch and plant interfaces.

An electronic skin that connects rigid inorganic electronic components with a multilayered stretchy liquid metal fibre mat using a hybrid liquid metal solder can offer high integration density while remaining soft, permeable and biocompatible.

Probabilistic-bit-based Ising machines implemented on field-programmable gate arrays can be used to train artificial intelligence networks with the same performance as software-based approaches while using fewer model parameters.
