The merits of a pedagogic and programmatic unification between physics and several engineering disciplines at the undergraduate level are discussed. Arguments for such a unification are presented, based on the strong overlap of core teaching material...

We demonstrate that nanocrystalline diamond films grown on highly doped silicon substrates can be patterned using a CO2 laser operating at a wavelength of 10.6 μm, where both low doped silicon and diamond exhibit negligible optical absorption. The pa... Read More about CO2 laser micromachining of nanocrystalline diamond films grown on doped silicon substrates.
