Use two-dimensional materials to design and fabricate neural resistance devices to realize logic operations

The human brain is an efficient computing system.
A single human neuron can perform Boolean operations, including non-linear exclusive OR (XOR) operations
.
However, to simulate this artificial neuromorphic system, several devices are usually required to complete a Boolean operation

Recently, Zhou Peng from Fudan University, Hu Weida from the Shanghai Institute of Technical Physics of the Chinese Academy of Sciences, and others have collaborated to fabricate neural resistance devices using the intrinsic polarity design of two-dimensional materials.
The logic operation is implemented in a single device, which greatly optimizes the complexity of the device.
It greatly reduces the system's computing energy consumption and highlights the application prospects of two-dimensional materials in artificial neuromorphic computing systems
.
The research was published in the latest issue of "Nature Electronics" with the title "Logic gates based on neuristors made from two-dimensional materials"

Article highlights:

1.
The logic operation of a single device is related to the polarity of the two-dimensional material
.
Bipolar tungsten diselenide (WSe ₂ ) can realize XNOR operation, p-type black phosphorus can realize NOR operation, and n-type molybdenum disulfide (MoS ₂ ) of different thickness can realize OR and AND operation
