Journal ArticleDOI
Large-area luminescent solar concentrators based on /`Stokes-shift-engineered/' nanocrystals in a mass-polymerized PMMA matrix
Francesco Meinardi,Annalisa Colombo,Kirill A. Velizhanin,Roberto Simonutti,Monica Lorenzon,Luca Beverina,Ranjani Viswanatha,Ranjani Viswanatha,Victor I. Klimov,Sergio Brovelli +9 more
TL;DR: In this article, Stokes-shift-engineered CdSe/CdS quantum dots are used to fabricate luminescent solar concentrators that are tens of centimetres long and do not exhibit reabsorption losses.
Journal ArticleDOI
Highly efficient large-area colourless luminescent solar concentrators using heavy-metal-free colloidal quantum dots
Francesco Meinardi,Hunter McDaniel,Francesco Carulli,Annalisa Colombo,Kirill A. Velizhanin,Nikolay S. Makarov,Roberto Simonutti,Victor I. Klimov,Sergio Brovelli +8 more
TL;DR: In this article, a large-area quantum dot-luminescent solar concentrators free of toxic elements is presented, with reduced reabsorption and extended coverage of the solar spectrum.
Journal ArticleDOI
Probing excitonic states in suspended two-dimensional semiconductors by photocurrent spectroscopy
Andrey Klots,Akm Newaz,Akm Newaz,Bin Wang,Bin Wang,Dhiraj Prasai,Halina Krzyzanowska,Junhao Lin,D. Caudel,Nirmal Ghimire,Jiaqiang Yan,Borislav Ivanov,Kirill A. Velizhanin,Arnold Burger,D. G. Mandrus,Norman Tolk,Sokrates T. Pantelides,Sokrates T. Pantelides,Kirill I. Bolotin +18 more
TL;DR: It is demonstrated that that substrate-related effects such as screening and disorder in currently available specimens mask many anticipated physical phenomena and limit device applications of TMDCs.
Journal ArticleDOI
Probing excitonic states in ultraclean suspended two-dimensional semiconductors by photocurrent spectroscopy
Andrey Klots,Akm Newaz,Bin Wang,Dhiraj Prasai,Halina Krzyzanowska,D. Caudel,Nirmal Ghimire,J.-Q. Yan,Borislav Ivanov,Kirill A. Velizhanin,Arnold Burger,D. G. Mandrus,Norman Tolk,Sokrates T. Pantelides,Kirill I. Bolotin +14 more
TL;DR: In this article, the authors demonstrate that the undesirable effects such as screening and disorder in currently available specimens mask many anticipated physical phenomena and limit device applications of semiconducting monolayer transition-metal dichalcogenides.
Journal ArticleDOI
Magnetooptics of Exciton Rydberg States in a Monolayer Semiconductor.
Andreas V. Stier,Nathan P. Wilson,Kirill A. Velizhanin,Junichiro Kono,Xiaodong Xu,Scott A. Crooker +5 more
TL;DR: The strongly field-dependent and distinct energy shifts of the 2s, 3s, and 4s excited neutral excitons permits their unambiguous identification and allows for quantitative comparison with leading theoretical models.
