Probing quantum nanostructures with near-field optical microscopy and (vice versa)
arXiv:cond-mat/9710162 · doi:10.1063/1.120868
Abstract
A theory is presented to show how near-field optical microscopy can be used to probe quantum nanostructures. Calculations are done for a quantum dot. Results for different tip/dot configurations and sizes show that near-field excitation can enhance light-hole transitions, excite selection-rule breaking transitions with rates comparable to allowed transitions, and map electron-hole pair wave functions. Conversely, dot response can be used to characterize tip near-fields.
