Artificial synapse developed for brain-like computing

Scientists have used scandium nitride (ScN), a semiconducting material with supreme stability and Complementary Metal-Oxide-Semiconductor (CMOS) compatibility, to develop brain-like computing. This invention can provide a new material for stable, CMOS-compatible optoelectronic synaptic functionalities at a relatively lower energy cost and hence has the potential to be translated into an industrial product.

The traditional computers have physically separated memory storage and processing units. As a result, it takes enormous energy and time to transfer data between these units during an operation. On the contrary, the human brain is a supreme biological computer that is smaller and more efficient due to the presence of a synapse (the connection between two neurons) that plays the role of both processor and memory storage unit. In the current era of artificial intelligence, the brain-like computing approach can help meet the escalating computational demands. The development of neuromorphic hardware aims at mimicking a biological synapse that monitors and remembers the signal generated by the stimuli. Scientists have been trying to create an artificial synaptic device that does not suffer from RC delays, exhibits large bandwidth, consumes low energy, and is stable, scalable, and CMOS-compatible.



A team of scientists at Bengaluru’s Jawaharlal Nehru Centre for Advanced Scientific Research (JNCASR), an autonomous institute of the Department of Science and Technology, Government of India, who were working on nitride-based materials have used their background for developing hardware for neuromorphic computing. They used ScN to develop a device mimicking a synapse that controls the signal transmission as well as remembers the signal.

This work by Dheemahi Rao and team demonstrate an artificial optoelectronic synapse with ScN thin films that can mimic synaptic functionalities like short-term memory, long-term memory, the transition from short-term to long-term memory, learning–forgetting, frequency selective optical filtering, frequency-dependent potentiation and depression, Hebbian learning, and logic-gate operations.

Compared to the existing materials used to demonstrate optoelectronic synapse, ScN is more stable, CMOS compatible, and can be seamlessly integrated with existing Si technology. It can act as a platform for both excitatory and inhibitory functions. The industrial processing techniques of ScN are similar to the existing semiconductor fabrication infrastructure. Response to the optical stimuli also has the advantage of possible integration with photonic circuits known for higher speed and broader bandwidth than electronic circuits.

What is HAARP?

HAARP (High Frequency Active Auroral Research Program) is a research program funded by the U.S. military and several other organizations. It was established to study the Earth's upper atmosphere and ionosphere, with the goal of understanding their effects on communication and navigation systems. The program used a high-frequency radio transmitter located in Gakona, Alaska, to generate and study powerful radio waves in the upper atmosphere. The facility has since been decommissioned and is no longer in operation.

HAARP has been the subject of various conspiracy theories, which claim that it was used for purposes such as weather control, mind control, and earthquakes. However, these claims are not supported by scientific evidence and have been widely discredited by the scientific community.
