“Quantitative strain mapping of InAs/InP quantum dots with 1 nm spatial resolution using dark field electron holography”. Cooper D, Rouvière J-L, Béché, A, Kadkhodazadeh S, Semenova ES, Dunin-Borkowsk R, Applied physics letters 99, 261911 (2011). http://doi.org/10.1063/1.3672194
Abstract: The optical properties of semiconductor quantum dots are greatly influenced by their strain state. Dark field electron holography has been used to measure the strain in InAsquantum dotsgrown in InP with a spatial resolution of 1 nm. A strain value of 5.4% ± 0.1% has been determined which is consistent with both measurements made by geometrical phase analysis of high angle annular dark field scanning transmission electron microscopy images and with simulations.
