Dual‐Function Interface Engineering for δ‐Phase‐Free Crystallization Toward Efficient and Stable FAPbI3 Perovskite Solar Cells

Advanced Functional Materials, EarlyView.
This work presents a dual‐function interface engineering strategy using PEACl to suppress the formation of the non‐perovskite δ‐FAPbI3 phase at the critical SnO2 buried interface. This approach enables the direct crystallization of the photoactive α‐phase, yielding highly efficient and stable rigid (25.6%) and flexible perovskite solar cells with ...

Quantum solution to the Newcomb's paradox [PDF]

We show that quantum game theory offers solution to the famous Newcomb's paradox (free will problem). Divine foreknowledge is not necessary for successful completion of the game because quantum theory offers a way to discern human intentions in such way ...

Quantum Time Arrows, Semigroups and Time-Reversal in Scattering [PDF]

, 2002
Two approaches toward the arrow of time for scattering processes have been proposed in rigged Hilbert space quantum mechanics. One, due to Arno Bohm, involves preparations and registrations in laboratory operations and results in two semigroups oriented ...

Exciton Binding Energy of Phosphorescent Emitter Molecules in Organic Light‐Emitting Diodes

Advanced Functional Materials, EarlyView.
Energy level alignment is key to efficient OLED design, yet determining LUMO energies remains challenging. A methodology based on field‐induced dissociation and kinetic Monte Carlo simulations is presented to extract LUMO energies of iridium‐based phosphorescent emitters from their exciton binding energy.

LANDAU LEVELS AND QUANTUM GROUP [PDF]

Modern Physics Letters A, 1994
We find a quantum group structure in two-dimensional motions of a nonrelativistic electron in a uniform magnetic field and in a periodic potential. The representation basis of the quantum algebra is composed of wave functions of the system. The quantum group symmetry commutes with the Hamiltonian and is relevant to the Landau level degeneracy.
