Background

Overview

This concept is fundamental to advancements in materials science and engineering, directly impacting the development of faster, more efficient computing and data storage technologies, which are critical for India's digital infrastructure and economic growth.

Strain engineering is a materials science technique that involves applying mechanical stress to a material at the atomic level to intentionally alter its physical properties, such as electrical conductivity, magnetic characteristics, or optical responses.

Facts & tables

Key facts

Mechanism

Involves applying mechanical pressure (squeezing/stretching) to atomic lattices.

Purpose

Aims to modify material properties like electrical conductivity or magnetic information storage.

Frequency Requirement

Crucial for achieving terahertz (THz) frequencies needed for next-generation technologies.

Driving Force

Recent research highlights electron pressure, rather than heat, as a dominant driving force for atomic motion.
