Advanced Functional Materials, Volume 35, Issue 12, March 18, 2025.The formate pseudo‐halide anion is strategically introduced at the buried interface to stabilize the intermediate phases formed during perovskite crystallization. The controlled crystallization enhances crystallinity and alleviates tensile strain, eliminating residual PbI2 near the buried interface.

Tidal Forces Around Black-Bounce-Reissner–Nordström Black Hole
UniverseThe central singularity present in black hole (BH) spacetimes arising in the general theory of relativity (GR) can be avoided by using various methods. In the present work we have investigated the gravitational effect of one of such spacetime known as a ...

Mass Functions of Supermassive Black Holes across Cosmic Time
Advances in Astronomy, 2012 The black hole mass function of supermassive black holes describes the evolution of the distribution of black hole mass. It is one of the primary empirical tools available for mapping the growth of supermassive black holes and for constraining ...

Stability of scalarized charged black holes in the Einstein–Maxwell–Scalar theory
European Physical Journal C: Particles and Fields, 2019 We analyze the stability of scalarized charged black holes in the Einstein–Maxwell–Scalar (EMS) theory with quadratic coupling. These black holes are labelled by the number of $$n=0,1,2,\ldots $$ n=0,1,2,… , where $$n=0$$ n=0 is called the fundamental ...

Scalarized charged black holes in the Einstein-Maxwell-Scalar theory with two U(1) fields
Physics Letters B, 2020 We investigate scalarized charged black holes in the Einstein-Maxwell-Scalar theory with two U(1) fields inspired by the N=4 supergravity. From the onset of the spontaneous scalarization (tachyonic instability of Reissner-Nordström black hole), these ...

Rotating Black Hole Thermodynamics with a Particle Probe
, 2011 The thermodynamics of Myers-Perry black holes in general dimensions are studied using a particle probe. When undergoing particle absorption, the changes of the entropy and irreducible mass are shown to be dependent on the particle radial momentum.

Physical Review D, 1992 Static solutions of large-$N$ quantum dilaton gravity in $1+1$ dimensions are analyzed and found to exhibit some unusual behavior. As expected from previous work, infinite-mass solutions are found describing a black hole in equilibrium with a bath of Hawking radiation.

Advanced Functional Materials, EarlyView.PBTTT‐OR‐R, a C14‐alkoxy/alkyl‐PBTTT polymer derivative, is of substantial interest for optoelectronics due to its specific fullerene intercalation behavior and enhanced charge‐transfer absorption. Comparing this polymer with (S) and without (O) homocoupling defects reveals that PBTTT‐OR‐R(O) forms stable co‐crystals with PC61BM, while PBTTT‐OR‐R(S ...

Entropy Function for Non-Extremal Black Holes in String Theory [PDF]
, 2007 We generalize the entropy function formalism to five-dimensional and four-dimensional non-extremal black holes in string theory. In the near horizon limit, these black holes have BTZ metric as part of the spacetime geometry.
