- [00:00:04.791]I'm Steve Ducharme.
- [00:00:06.360]I'm a member of the faculty here
- [00:00:07.755]in the Department of Physics & Astronomy
- [00:00:09.212]at the University of Nebraska–Lincoln.
- [00:00:11.690]I work on studying crystals that have
- [00:00:14.422]built-in electric fields.
- [00:00:16.256]These are particularly useful,
- [00:00:17.593]for instance, electronics technologies,
- [00:00:19.958]solar cells, memories, and so forth.
- [00:00:22.494]And as we want to miniaturize these things
- [00:00:25.055]we need to understand how the crystals behave
- [00:00:26.680]at smaller and smaller scales.
- [00:00:29.313]And the new tools of nanotechnology tools,
- [00:00:31.370]for instance, allow us to probe
- [00:00:33.199]the electrical properties of small nanostructures,
- [00:00:36.529]meaning a few hundred atoms at a time.
- [00:00:39.312]And that allows us to understand better how they behave,
- [00:00:41.635]to perhaps design new technologies based on these.
- [00:00:45.979]So it really is a back-and-forth.
- [00:00:49.767]We in science use these tools to study better,
- [00:00:54.363]say, smaller and more elusive objects,
- [00:00:56.575]and then we can help design newer tools
- [00:00:59.193]that can be used in industry and also in science
- [00:01:01.586]to advance that. That's been true
- [00:01:03.352]since even the early days of semiconductors.
- [00:01:05.511]I'll offer a computer [unknown]
- [00:01:07.246]born in research labs
- [00:01:09.215]and they, and what we learn from them
- [00:01:12.798]comes from the use of those technologies.
