If I am correct, it structures as tetrahedral arrangements wherein all the tetrahedra are connected, but have random orientations. So, what I am envisioning to do is create a supercell of about 20 tetrahedra, and orient these 20 based on a Monte Carlo method. Is this the correct way to simulate the amorphous SiO2? And if it is, are there any suggestions for how to use a Monte Carlo method to find the atomic positions?<br></div>I'd appreciate any feed back.<br></div>Thanks,<br></div>Sarah<br></div>
