Spintronics is a technology that utilizes the spin of electrons - in addition to their charge - in order to store and process information. Unlike traditional electronics, which rely on the movement of electrons to perform their functions, spintronics uses the intrinsic angular momentum of electrons to achieve the same results. Spintronics offers the potential to address some limitations of traditional, charge-based computing and it has the potential for developing new types of devices such as spin-based transistors and logic gates.

Recent investigations suggest that topological semimetals reveal unique properties that can enable unprecedented functionalities for future electronics. New research results shed light on the specifics of electron transport in quasi-one-dimensional topological Weyl semimetals and can be important for their proposed applications as downscaled interconnects. The results obtained in this work can be used for developing assessment methodologies for the reliability of topological semimetals.

Researchers show how MXenes' rich chemistry can be used to create doping-free 2D transistors with intrinsically low resistive contacts while maintaining balance mode operation. With a suitable functional termination, MXenes can become a semiconductor or a metal with a different work function. The researchers exploit this unique property of MXene to propose a Schottky barrier transistor, which can be implemented with a bare MXene by converting it to a semiconductor in the channel region with strategic functionalization.

Two-dimensional (2D) semiconductors, like transition-metal dichalcogenides, have become a competitive alternative to traditional semiconducting materials in the post-Moore era, and caused worldwide interest. However, before they can be used in practical applications, some key obstacles must be resolved. One of them is the large electrical contact resistances at the metal-semiconductor interfaces. Researchers have proposed a brand-new contact resistance lowering strategy of 2D semiconductors with a good feasibility, a wide generality and a high stability.

Researchers introduce spin orbit torque (SOT) devices to experimentally realize in-memory analogue mathematical operations such as summation, subtraction and four-quadrant multiplication, to implement general-purpose applications such as image or signal processing for edge computing. In addition to nonvolatility and scalability, the CMOS-compatible SOT technique further possesses low energy consumption, high speed and endurance. Therefore, SOT devices offer an avenue for dense in-memory analogue computing paradigms.

The goal of the electronics industry has always been to build durable devices with stable performance that last a very long time. Self-destructing, transient electronics however, are designed with the exact opposite goal: to dissolve harmlessly into their surroundings after functioning for a predetermined amount of time. Researchers now demonstrate novel biodegradable, recyclable, conductive, flexible, and printable materials that can be applied across many electronic devices to serve as a cornerstone for the development of ecofriendly and recyclable electronics.

Organic semiconductors (OSCs) are a class of semiconductor materials consisting of conjugated molecules or polymers. Compared to inorganic semiconductors, OSCs have distinctive advantages including being solution-processable, suitable for low-cost and large-area fabrication of electronics, and applicable to flexible/stretchable electronics, among others. Given the importance of doping techniques for semiconductors, it is highly attractive to establish doping methodologies for OSCs similar to that for silicon. This would simplify the difficulty and cost of synthesizing different types of OSCs for various applications, as well as lead to interesting structures such as organic PN homojunctions.
