Volatile threshold switching memristor: An emerging enabler in the AIoT era

Wenbin Zuo et al.

Summary: With the rapid development and integration of artificial intelligence and the internet-of-things, artificial intelligence of things (AIoT) has become a promising technology that is changing people's daily lives. The massive growth of data generated from devices poses challenges for AIoT systems in terms of information collection, storage, processing, and communication. This article introduces volatile threshold switching memristors, which play important roles in high-density storage, energy-efficient computing, and hardware security for AIoT systems. The categories and characteristics of volatile threshold switching devices are described, and the switching mechanisms of these devices are discussed and summarized. The article also focuses on the applications of volatile threshold switching memristors in various areas such as 3D cross-point memory technology, neuromorphic computing, hardware security, and others. The major challenges and future prospects of volatile threshold switching memristors are presented.

Chemical-vapor-deposited 2D VSe2 nanosheet with threshold switching behaviors for Boolean logic calculations and leaky integrate-and-fire functions

Lun Zhong et al.

Summary: In this study, VSe2 nanosheets were synthesized using chemical vapor deposition and underwent a phase transition from 1T to 2H through annealing. The annealed VSe2 nanosheets exhibited reliable threshold switching (TS) behavior with good endurance, repeatability, and environmental stability. The VSe2 memristor demonstrated the ability to perform logic operations and simulate leaky integrate-and-fire (LIF) activity. This research provides a feasible approach to TS behaviors, expanding the applications of VSe2 materials and offering potential candidates for Boolean logic calculations and LIF functions.

Charge density wave states in phase-engineered monolayer VTe2

Zhi-Li Zhu et al.

Summary: This study investigates the charge density wave (CDW) states in monolayer H-VTe2 induced by phase-engineering from T-phase VTe2. The phase transition between T- and H-VTe2 is revealed, and a stable 2 root 3 x 2 root 3 CDW superlattice is observed in H-VTe2. These findings provide a promising way for manipulating CDWs in 2D materials and show great potential in nanoelectronics applications.

Role of Joule heating in the electro-induced metal-insular transition of a composite film filled with VO2

Xiaoning Sun et al.

Summary: Vanadium dioxide undergoes reversible transition from insulating to metallic phase when triggered by stimuli such as heat and electric fields. This study used a hydrothermal method to prepare nano-VO2 particles with phase transition characteristics, and established models for electro-induced phase transition in VO2-filled Polyethylene glycol. The analysis revealed the impact of electrode-gap effect on phase-transition voltage and examined the formation of high-temperature conductive channels during the electro-induced phase transition.
