Strained Silicon

When silicon is mechanically stressed, it alters its electrical and optical characteristics, resulting in strained silicon. This makes the development of next-generation optical devices on strained silicon a promising substrate.
The ability to use strained silicon to make devices with improved optical efficiency and bandwidth is one of its main benefits. This is due to the fact that strained silicon can be utilized to modify silicon's band structure, enabling more effective light absorption and emission.
Devices that are more resistant to radiation damage can also be made using strained silicon. This is due to the fact that stretched silicon is more radiation-resistant than conventional silicon since it has a lower fault density.
Although the development of optical devices using strained silicon is still in its infancy, there has been a great deal of advancement in recent years. For instance, strained silicon lasers, LEDs, and photodetectors have been created by researchers and work better than conventional silicon devices.
A promising basis for the creation of next-generation optical devices is strained silicon. It may make it possible to create gadgets with increased radiation resistance, bandwidth, and efficiency. Numerous uses in computation, sensing, and optical communications may result from
