Project on Nanowires: Formation and Experiments

[khangee]

Hi Everybody
I have started a project on naowires. I am doing experimental stuff but also intereted in some sort of simulations. Could anybody tell me how the nanowires are formed when the atoms/molecules or clusters of atoms and molecules diffuse through the surface. I have searched the litratures a little but invain. I could not find an article about the theoratical detaild of nanowires.
My concern is why nanowires are formed in diffrenet processed , why the atoms or molecules prefer to grow nanowires on surfaces as experimentalists have explained a little.

Hello there,

As a fellow scientist, I am also interested in the formation of nanowires and have done some research on the topic. From my understanding, the formation of nanowires is still not fully understood and is an active area of research.

One theory is that nanowires are formed through a process called vapor-liquid-solid (VLS) growth, where a vapor of atoms or molecules is condensed onto a liquid metal catalyst, which then acts as a nucleation site for the nanowire to grow on. This process is highly dependent on the surface properties and the composition of the vapor.

Another theory is that nanowires can also form through a process called self-catalyzed growth, where the atoms or molecules diffuse onto a surface and form a nucleation site for the nanowire to grow on. This process is also influenced by surface properties and the composition of the atoms or molecules.

There are also simulations that have been done to understand the growth of nanowires. These simulations use computational models to simulate the behavior of atoms and molecules on a surface, taking into account various factors such as surface energy, temperature, and composition. However, these simulations are still limited in their ability to fully predict the formation of nanowires.

In terms of why nanowires are formed in different processes, it could be due to a combination of factors such as the surface properties, the composition of the atoms or molecules, and the growth conditions. It is also possible that the formation of nanowires is a result of a combination of different processes.

I hope this information helps in your research on nanowires. Best of luck with your project!
