Hi all,
I wonder whether anybody could help me finding the surface energy value of the interface between silicon and SiO2...
Thanks in advance !

Hi Mr. G,

The surface tension of silicon is a material property that describes the energy required to increase the surface area of a silicon sample. It is typically measured in units of Joules per square meter (J/m²) or dynes per centimeter (dyn/cm). However, the surface energy value of the interface between silicon and SiO2 is not a well-defined property and can vary depending on the specific conditions and methods used for measurement. Additionally, it can also vary depending on the crystal orientation and surface preparation of the silicon sample.

One approach to estimating the surface energy value of the silicon-SiO2 interface is through contact angle measurements. This method involves placing a droplet of liquid on the surface and measuring the angle at which it makes contact with the surface. The Young-Dupre equation can then be used to calculate the surface energy based on the contact angle and the known surface energies of the liquid and solid materials.

Another approach is through molecular dynamics simulations, which can provide a theoretical estimation of the surface energy at the interface based on the atomic interactions between silicon and SiO2 molecules.

I hope this information helps in your search. Best of luck!
