[Illinois] Nano EP Seminar Series: Dipole Instabilities in AlGaN/GaN Heterostructures and the Direct Generation of Millimeter-Wave Oscillations and Intrinsic Tristability in RTDs
26 Nov 2012 | | Contributor(s):: Paul Douglas Yoder
Negative differential drift velocity in wurtzite GaN has been verified experimentally, yet in spite of the wealth of documented theoretical investigations of GaN-based Gunn diodes, not a single such device has yet been demonstrated. The likelihood of realizing GaN-based k-space transfer devices...
[Illinois] Nano-EP Seminar Series: Nanogenerators and piezotronics - from basic science to novel applications
26 Nov 2012 | | Contributor(s):: Zhong Lin Wang
Developing wireless nanodevices and nanosystems is of critical importance for sensing, medical science, environmental/infrastructure monitoring, defense technology and even personal electronics. It is highly desirable for wireless devices to be self-powered without using battery. We have...
