Giant alloyed hot injection shells enable ultralow optical gain threshold in colloidal quantum wells
Altıntaş, Yemliha; Güngör, Kıvanç; Gao, Y.; Sak, Mustafa; Quliyeva, Ulviyya; Bappi, G.; Mutlugün, Evren; Sargent, E. H.; Demir, Hilmi Volkan (American Chemical Society, 2019)As an attractive materials system for high-performance optoelectronics, colloidal nanoplatelets (NPLs) benefit from atomic-level precision in thickness, minimizing emission inhomogeneous broadening. Much progress has been ... -
Highly stable multicrown heterostructures of type-II nanoplatelets for ultralow threshold optical gain
Dede, Didem; Taghipour, Nima; Quliyeva, Ulviyya; Sak, Mustafa; Kelestemur, Yusuf; Güngör, Kıvanç; Demir, Hilmi Volkan (American Chemical Society, 2019)Solution-processed type-II quantum wells exhibit outstanding optical properties, which make them promising candidates for light-generating applications including lasers and LEDs. However, they may suffer from poor colloidal ... -
Highly stable, near-unity efficiency atomically flat semiconductor nanocrystals of CdSe/ZnS hetero-nanoplatelets enabled by ZnS-Shell hot-injection growth
Yemliha, Yemliha; Quliyeva, Ulviyya; Güngör, Kıvanç; Erdem, Onur; Kelestemur, Yusuf; Mutlugün, Evren; Kovalenko, M.; Demir, Hilmi Volkan (WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim, 2019)Colloidal semiconductor nanoplatelets (NPLs) offer important benefits in nanocrystal optoelectronics with their unique excitonic properties. For NPLs, colloidal atomic layer deposition (c‐ALD) provides the ability to produce ... -
Ultrathin highly luminescent two-monolayer colloidal CdSe nanoplatelets
Delikanlı, Savaş; Yu, G.; Yeltik, Aydan; Bose, S.; Erdem, Talha; Yu, J.; Erdem, Onur; Sharma, Manoj; Sharma, Vijay Kumar; Quliyeva, Ulviyya; Shendre, S.; Dang, C.; Zhang, D.; Sum, T.; Fan, W.; Demir, Hilmi Volkan (WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim, 2019)Surface effects in atomically flat colloidal CdSe nanoplatelets (NLPs) are significantly and increasingly important with their thickness being reduced to subnanometer level, generating strong surface related deep trap ...
