Silicon surface tension

  1. Nov 8, 2005 #1
    Hi all,
    I wonder whether anybody could help me finding the surface energy value of the interface between silicon and SiO2...
    Thanks in advance !!

    There are two ways. the most correct way is to execute ab initio calculations with software like Castep, Siesta, Abinit. These calculations will give you the required data

    The second way is more general. Just look at the band bending at the Si/SiO2 interface. These energy charts are very well known and can be found anywhere on the net. Just do a little googling.

    It all depends on what exactly you are looking for.

    For example, i have an Italian friend at IMEC who is currently studying the influence on the surface stress of silicon when you incorporate Nitrogen. This system is used in transistor technology to boost up the electron mobility in the Si-substrate on a MOSFET.

    Check out the INTEL webpage for more info in Si3N4 etc
