- [00:00:05.147]Hi, my name is Xia Hong
- [00:00:06.437]I'm a physics professor at the
- [00:00:08.607]University of Nebraska–Lincoln.
- [00:00:10.704]I would say the development of nanotechnology
- [00:00:14.659]is always a strong motivation
- [00:00:16.498]for scientists to pursue developing the new materials
- [00:00:20.940]or searching for new physics.
- [00:00:23.244]As a scientist I'm always thrilled to see
- [00:00:26.686]my research actually would have impact
- [00:00:29.145]for the development of nanotechnology.
- [00:00:31.380]For example, over the last five decades,
- [00:00:34.349]I would say electronics are dominated by
- [00:00:36.822]a single material, that is silicon,
- [00:00:38.905]but now the capacity of silicon can not
- [00:00:41.471]actually host the rapidly developing functionalities
- [00:00:46.723]required for nanoelectronics.
- [00:00:49.034]So now it is there are basically two materials
- [00:00:51.344]we're increasingly investigating.
- [00:00:54.448]The first one is intrinsically 2D materials.
- [00:00:57.099]They're light, they're atomically [unknown],
- [00:01:00.188]you can make the device really, really small.
- [00:01:02.254]Another one is because we have to pack
- [00:01:04.378]so many devices in a very small [unknown] scale
- [00:01:07.690]you can imagine the power density becomes
- [00:01:09.836]very, very high.
- [00:01:11.387]For example, your cell phone gets really hot,
- [00:01:14.373]or something will even get burned.
- [00:01:17.014]So what I pursue is actually looking for
- [00:01:19.513]ways to have low-power electronics developed.
- [00:01:23.678]We are also developing a material where you can
- [00:01:26.365]control the function of the device not using
- [00:01:30.223]electrical current but using voltage.
- [00:01:32.637]So the way we do it is actually interfacing two materials,
- [00:01:36.693]one intrinsically has a magnetic functionality,
- [00:01:39.452]the other has a building electric dipole moment.
- [00:01:43.511]So we are hoping to control the magnetic properties
- [00:01:46.629]using the dipole moment.
- [00:01:49.116]So I would say yes, overall, what we want to do
- [00:01:53.137]is actually develop new materials and
- [00:01:55.300]new functionalities that will eventually be employed
- [00:01:59.729]in the technology.
