Piezotronics in 2D Piezoelectric Semiconductors
01 Apr 2016 | | Contributor(s):: Wenzhuo Wu
Monolayer MoS2 and other TMDCs have been theoretically predicted to exhibit piezoelectricity due to the strain induced lattice distortion and associated ion charge polarization, suggesting possible applications of these 2D nanomaterials in nano-scale electromechanical devices that take advantage...

Fundamentals of Piezoelectric and Ferroelectric Materials - Part 2
17 Mar 2014 | | Contributor(s):: Susan Trolier-McKinstry, ASSIST ERC
This presentation is an introduction to materials of interest for piezoelectric and ferroelectric applications. The lecture begins with basic definitions of pyroelectricity, piezoelectricity, and ferroelectricity, and the link between these and the symmetry shown by the material is explained....

Why quantum dot simulation domain must contain multi-million atoms?
04 Jan 2013 | | Contributor(s):: Muhammad Usman
The InGaAs quantum dots obtained from the self-assembly growth process are heavily strained. The long-range strain and piezoelectric fields significantly modifies the electronic structure of the quantum dots. This imposes a critical constraint on the minimum size of the simulation domain to study...
Excited State Spectroscopy of a Quantum Dot Molecule
16 Dec 2011 | | Contributor(s):: Muhammad Usman
Atomistic electronic structure calculations are performed to study the coherent inter-dot couplings of the electronic states in a single InGaAs quantum dot molecule. The experimentally observed excitonic spectrum by Krenner et al (Phys. Rev. Lett. 94 057402, 2005) is quantitatively reproduced,...
