Colloidal CsPbBr3 Perovskite Nanocrystals: Luminescence beyond Traditional Quantum Dots.
Abhishek Swarnkar,Ramya Chulliyil,Vikash Kumar Ravi,Mir Irfanullah,Arindam Chowdhury,Angshuman Nag +5 more
TL;DR: This work highlights the advantages in both ensemble and single-nanocrystal PL of colloidal CsPbBr3 nanocrystals (NCs) over the traditional cQDs and investigates batch-to-batch reproducibility of NCs exhibiting PL peaks within ±1 nm.
Journal ArticleDOI
Graphene analogues of BN: novel synthesis and properties.
Angshuman Nag,Kalyan Raidongia,K. P. S. S. Hembram,Ranjan Datta,Umesh V. Waghmare,C. N. R. Rao,C. N. R. Rao +6 more
TL;DR: It is found that the mechanical stability of BN with respect to out-of-plane deformation is quite different from that of graphene, as evident in the dispersion of their flexural modes.
Journal ArticleDOI
Metal-free Inorganic Ligands for Colloidal Nanocrystals: S2–, HS–, Se2–, HSe–, Te2–, HTe–, TeS32–, OH–, and NH2– as Surface Ligands
Angshuman Nag,Maksym V. Kovalenko,Jong-Soo Lee,Wenyong Liu,Boris Spokoyny,Dmitri V. Talapin,Dmitri V. Talapin +6 more
TL;DR: It is shown that the key aspects of Pearson's hard and soft acids and bases (HSAB) principle can be applied to the bonding of molecular species to the nanocrystal surface and facilitated the charge transport between individual nanocrystals.
Journal ArticleDOI

TL;DR: A comprehensive review of metal-halide perovskite nanocrystals can be found in this article, where researchers having expertise in different fields (chemistry, physics, and device engineering) have joined together to provide a state-of-the-art overview and future prospects of metalhalide nanocrystal research.
Journal ArticleDOI
Terahertz Conductivity within Colloidal CsPbBr3 Perovskite Nanocrystals: Remarkably High Carrier Mobilities and Large Diffusion Lengths
Gurivi Reddy Yettapu,Debnath Talukdar,Sohini Sarkar,Abhishek Swarnkar,Angshuman Nag,Prasenjit Ghosh,Pankaj Mandal +6 more
TL;DR: These results confirm a negligible influence of surface defects in trapping charge carriers, which in turn results into desirable intrinsic transport properties, from the perspective of device applications, such as remarkably high carrier mobility, large diffusion length, and high luminescence quantum yield.
