Imagine a group of scientists exploring a mysterious new land where they discover an extraordinary type of stone with unique properties. These special stones, called transition metal dichalcogenides (TMDCs), hold the key to unlocking new possibilities in electronic devices. In their exciting adventure, the scientists stumbled upon a magical memristive device made from a layered material called tungsten disulfide (WS2). By introducing removable oxygen ions into WS2 through a special process, they were able to create a volatile memristor with remarkable resistive switching capabilities. This breakthrough led them to develop an arithmetic logic unit function and combinational logic circuits that could revolutionize computing. But that’s not all! Using the characteristics of excitatory postsynaptic current, paired-pulse facilitation, and spike rate dependent plasticity, they successfully achieved real-time numerical system conversion. Just like discovering a hidden treasure, this work unveils the immense potential of 2D memristive devices for future applications in arithmetic logic. Explore the fascinating research behind this groundbreaking discovery!
The intriguing properties of two-dimensional (2D) transition metal dichalcogenides (TMDCs) enable the exploration of new electronic device architectures, particularly the emerging memristive devices for in-memory computing applications. Implementation of arithmetic logic operations taking advantage of the non-linear characteristics of memristor can significantly improve the energy efficiency and simplify the complexity of peripheral circuits. Herein, we demonstrate an arithmetic logic unit function using a lateral volatile memristor based on layered 2D tungsten disulfide (WS2) materials and some combinational logic circuits. Removable oxygen ions were introduced into WS2 materials through oxygen plasma treatment process. The resistive switching of the memristive device caused by the thermophoresis-assisted oxygen ions migration has also been revealed. Based on the characteristics of excitatory postsynaptic current (EPSC), paired-pulse facilitation (PPF), and spike rate dependent plasticity (SRDP), a real-time numerical system convertor was successfully accomplished, which is a significant computing function of arithmetic logic unit. This work paves a new way for developing 2D memristive devices for future arithmetic logic applications.
