The improved and newly created software allows for massively-parallel computations for nanosystems with numbers of atoms exceeding 100 million. Results of large scale atomistic calculations have shown a significant effect of external strain on spectral properties of nanowires and nanowire quantum dots. A fundamental role of quantum dot shape symmetry and lattice composition fluctuations [Phys. Rev. B 91, 085303 (2015)]. on excitonic spectra has also been found.
Back to the beginning...Sonata Bis projectIn this project, we intend to formulate theoretical description and perform large-scale calculations of spectral properties of silicon nanodevices doped with single impurity atoms. Single dopant embedded in a host environment of millions of silicon atoms forms a complicated nanosystem where every atoms must be accounted for individually. In other words: every atom matters. Our approach will therefore utilize the atomistic tight-binding method that naturally incorporates effects of quantum confinement, external fields, and atomistic effects such as interfaces steps and composition disorder. We aim to apply our methodology to solve currently untraceable problems where impurity wave-function extends over ten millions of atomic sites. Thanks to close collaboration with the National Institute of Standards and Technology (NIST) we will have the unique ability to correlate the measured and calculated data. We hire PhDs now!Back to the beginning... |
