| fluorofactor | if grow a silicon dioxide on a silicon what happen grow of a semiconductor on a silicon dioxide? | 05:21 |
| fluorofactor | silicon dioxide is a morphous? | 05:22 |
| fluorofactor | is too a semiconductor on a silicon dioxide a morphous? | 05:22 |
| azonenberg | fluorofactor: grow a semiconductor on sio2 | 05:23 |
| azonenberg | which semiconductor | 05:23 |
| azonenberg | and grown how | 05:23 |
| azonenberg | on what kind of oxide | 05:23 |
| azonenberg | PECVD oxide for example is usually pretty amorphous | 05:23 |
| azonenberg | but you can get monocrystalline silica aka quartz | 05:23 |
| azonenberg | and how are you depositing the semiconductor on the oxide | 05:23 |
| azonenberg | i mean, you might be able to do epitaxial Si on top of single-crystal SiO2 and get a monocrystalline film | 05:24 |
| azonenberg | with any other deposition technique you would likely end up with poly-si | 05:24 |
| fluorofactor | is a epitaxy on amorphous silicon dioxide give a nice a crystal? | 05:27 |
| azonenberg | Epitaxy on a non-crystalline surface isnt possible | 05:27 |
| azonenberg | by definition you're creating a new film but based on an existing crystal | 05:27 |
