(a) Geometric configuration of SNMs with R = 1 and W = 4. Yellow and white balls represent Si and H atoms, respectively. Energy band structures of SNMs with odd (b) and even (c) W . (d) The band gap of SNM as a function of W with R = 1 and 2. (e) Band gap is plotted versus the quantity . ( N removed is the number of removed Si atoms, and N total is equal to the number of atoms before the holes are made in the unit cell.) The black line represents a linear fit to the data.
