@article { , title = {High pressure as a tool to tune electronic coupling in self-assembled quantum dot nanostructures}, abstract = {High pressure provides an efficient way of controlling the electronic properties of semiconductor nanostructures. We use pressure to tune electronic coupling in stacks of self-assembled quantum dots (SAQDs). The coupling occurs as soon as the distance and the height of the barriers between the dots are sufficiently small to permit interaction between the wavefunctions of electrons in adjacent dots. We demonstrate experimental evidence that application of pressure reduces and may quench the coupling. This happens because, under pressure, the inter-dot barriers become higher and hence less transparent for electron wavefunctions. The effect was revealed by means of photoluminescence spectroscopy and confirmed by theoretical modelling.}, doi = {10.1002/pssb.200405235}, eissn = {1521-3951}, issn = {0370-1972}, issue = {14}, journal = {PHYSICA STATUS SOLIDI B-BASIC SOLID STATE PHYSICS}, note = {Output ID 22995.}, pages = {3257-3262}, publicationstatus = {Published}, publisher = {Wiley}, url = {https://hull-repository.worktribe.com/output/391499}, volume = {241}, keyword = {Specialist Research - Other, Electronic, Optical and Magnetic Materials, Condensed Matter Physics}, year = {2004}, author = {Itskevich, I.
