Sentences with phrase «grow on silicon»

The RPI team made the paper battery by first growing an array of carbon nanotubes on a silicon surface and then covering the array in dissolved cellulose (the main constituent of paper).

In their new work, the team grew quantum dots directly on silicon substrates using a technique known as molecular beam epitaxy, or MBE («epitaxy» refers to the process of growing one crystal on top of another, with the orientation of the top layer determined by that of the bottom).
