Using epitaxial AlGaN/AlN quantum wells as a test system, we observe the emergence of additional features in the loss spectrum with the increasing Ga content. A comparison of the observed spectra with ab-initio theory reveals that the origin of these spectral features lies in excitations of 3d-electrons contributed by Ga. We find that these modes differ in energy from the valence electron plasmons in Al1–xGaxN due to the different polarizabilities of the d electrons. Finally, we study the dependence of observed spectral features on the Ga content, lending insights into the origin of these spectral features, and their coupling with electron-hole excitations.}, number={6}, journal={Applied Physics Letters}, publisher={AIP Publishing}, author={Dhall, Rohan and Vigil-Fowler, Derek and Houston Dycus, J. and Kirste, Ronny and Mita, Seiji and Sitar, Zlatko and Collazo, Ramon and LeBeau, James M.}, year={2018}, month={Feb}, pages={061102} } @article{zheng_fahrenholtz_hackett_ding_day_dhall_marrs_gross_singh_bierbach_2017, title={Large-Pore Functionalized Mesoporous Silica Nanoparticles as Drug Delivery Vector for a Highly Cytotoxic Hybrid PlatinumAcridine Anticancer Agent}, volume={23}, ISSN={["1521-3765"]}, DOI={10.1002/chem.201604868}, abstractNote={Abstract}, number={14}, journal={CHEMISTRY-A EUROPEAN JOURNAL}, author={Zheng, Ye and Fahrenholtz, Cale D. and Hackett, Christopher L. and Ding, Song and Day, Cynthia S. and Dhall, Rohan and Marrs, Glen S. and Gross, Michael D. and Singh, Ravi and Bierbach, Ulrich}, year={2017}, month={Mar}, pages={3386–3397} }
