Band gap predictions of double perovskite oxides using machine learning

open access: yesCommunications Materials, 2023
The compositional and structural variety inherent to oxide perovskites spawn wide-ranging applications. In perovskites, the band gap Eg, a key material parameter for these applications, can be optimally controlled by varying the composition.

Investigation on the predictive power of tolerance factor τ for A-site double perovskite oxides.

open access: yesDalton Transactions, 2023
We have used a recently introduced new tolerance factor τ to create a stability map of all possible A-site double perovskite titanates AA'Ti2O6 and niobates AA'Nb2O6.

Highly Controllable Synthesis and DFT Calculations of Double/Triple-Halide CsPbX3 (X = Cl, Br, I) Perovskite Quantum Dots: Application to Light-Emitting Diodes

open access: yesNanomaterials, 2019
Although all-inorganic CsPbX3 (X = Cl, Br, I) perovskite quantum dots (PQDs) have evoked exciting new opportunities for optoelectronic applications due to their remarkable optical properties, their emission color tunability has not been investigated to ...

Electronic spin state of ferric iron in Al-bearing perovskite in the lower mantle [PDF]

open access: yes, 2005
We investigate the effect of pressure on the electronic spin state of ferric iron on Al-bearing MgSiO3-perovskite using first-principle computations. Ferric iron (6.25 mol%) and Al ( 6.25 mol%) substitute for Mg and Si respectively.

Lead-free perovskite and double perovskite solar cells

open access: yesIOP Conference Series: Materials Science and Engineering, 2020
Abstract The toxicity and instability of lead-halide perovskite materials in the solar cells are yet demands must be resolved to vie to find alternatives of free lead-based halide perovskites and double perovskite materials. Here we report on the experimental synthesis of a new family of lead-free inorganic halide double perovskites ...
