Nanowires and Silicon whiskers, a new age of technology

The world has seen major developments in the field of technology in recent years. One of the most booming field is nanotechnology and nanowires. Associate professor, Moneesh Upmanyu of Northeaster University explains more about the same in his journal ‘Nature Communications’. Professor Moneesh has been able to use computational tools in order to understand the growth of nanowires and droplets. “The droplet is able to multitask on several levels. That is the beauty of this growth technique.” Mr Upmanyu said. This might just be a very good leap in the research field. 


A nanowire is a wire with a dimension of less than one nanometre (10^-9 m). Gradually, the substance sculpts into different shape and sizes when liquid metal is dropped on it. Gradually it starts to uniformly wrap itself around the nanowire. Slowly, we can see a wire-shaped form of the nanowire. This layer by layer growth of the nanowire is what’s driving scientists crazy about this experiment. 


There can be various applications of this experiment. The most important one is a new way to design and manufacture solar cells and LED lighting. Nanocrystals formed from the droplets have shown solid-state light-emitting applications. This model has showcased high colour purity and a wide range of visible wavelengths. Hence, this model of creating nanocrystals can be key to manufacturing high-performance devices in the future. This model could also be merged with Quantum Dot technology.  In addition to this, the use of these quantum dots and nanowires can also help create high-quality solar cells. 

A lot is still unknown about nanocrystals and how we can make use of them. However, Mr Moneesh believes it is the key to an efficient and bright future. It will play a key role in the growth of chemistry, surface science, and much more.
