About this Research Topic
Modern computers use von-Neumann architecture with physically separate logic unit (Si-based CMOS) and memory unit (eg. SRAM, DRAM, SSDs). In recent time, scaling of conventional logic and memory devices has become challenging due to cost, reliability and limited performance gains for advanced technology nodes. Furthermore, von-Neumann architecture is inherently inefficient to handle data-centric computing. Hence, novel spin-based electronic devices are being extensively pursued which can either complement or replace conventional logic and memory devices. To make such spintronics devices attractive for commercialization will require either:
1. Improvement in terms of densities, speed, energy consumption etc. via material research (e.g. high spin hall angle materials) or novel device concepts (eg. voltage controlled spin devices)
2. Utilization of unique properties of spintronics devices (eg. oscillatory behavior or stochasticity) to implement unconventional computing systems to break von-Neumann bottleneck.
In this research topic, we are interested in manuscripts with focus on:
1. Experimental/theoretical work on material/material system to improve performance of existing spintronics devices.
2. Spintronics devices with novel operating mechanism to control or read magnetism.
3. Demonstration/proposal of spintronics devices (logic or memory) with unique characteristics and potential to be used in unconventional computing systems such as neuromorphic computing, probabilistic computing etc.
4. Simulations of computing systems capable of efficiently solving problems such as image recognition, optimization etc. utilizing intrinsic properties of emerging spintronics devices.
5. Novel approaches to create physics-based model of spintronics devices for large-scale circuit and system simulations.
