Intermixing‐Driven Growth of Highly Oriented Indium Phosphide on Black Phosphorus

open access: yesAdvanced Functional Materials, EarlyView.
This study demonstrates controlled intermixing and compound formation at the In/black phosphorus (BP) interface, leading to highly oriented InP formation. Comprehensive structural and electrical analyses reveal tunable bandgap behavior governed by competing BP thinning and charge‐transfer effects, underscoring the critical role of interfacial compound ...

Efficient NiOx Hole Transport Layers Enabled by Multifunctional MXenes for High‐Performance Tin‐Lead Perovskite Solar Cells

open access: yesAdvanced Functional Materials, EarlyView.
An efficient NiOx HTL is successfully prepared by introducing MXene as an additive without further surface modification to fabricate high‐performance FASn0.5Pb0.5I3 perovskite solar cells. The introduction of MXene contributes to improved conductivity of NiOx, better aligned at NiOx/perovskite interfaces, and enhanced quality of perovskite films ...

Toughening β‐Ga2O3 via Mechanically Seeded Dislocations

open access: yesAdvanced Functional Materials, EarlyView.
β‐Ga2O3 is promising for next‐generation semiconductors but its brittleness limits flexible and high‐precision applications. Here, mechanically seeded dislocations introduced by surface deformation improved damage tolerance in (001) β‐Ga2O3. Nanoindentation and characterization show dislocations suppress cleavage cracks by enabling stable plastic ...

Circular‐Polarization‐Sensitive Organic Photodetectors with a Chiral Nanopatterned Electrode Inverse‐Designed by Genetic Algorithm

open access: yesAdvanced Functional Materials, EarlyView.
A chiral photodetector capable of selectively distinguishing left‐ and right‐handed circularly polarized light is experimentally demonstrated. The device, which features a nanopatterned electrode inverse‐designed by a genetic algorithm within a metal–dielectric–metal nanocavity that incorporates a vacuum‐deposited small‐molecule multilayer, exhibits ...

An Upper Bound on the Zero-Crossing Distribution*

Bell System Technical Journal, 1968
Let Q(T) equal the probability that a random process, x(t), does not cross the zero axis in a given interval of length T. A family of upper bounds for Q(T) is derived with only weak restrictions imposed on x(t) and it is shown that for gaussian random processes only one member of the family provides useful formulae.

Upper bound on total cross sections

Letters in Mathematical Physics, 1977
It is shown, under certain assumptions, that if the Nth derivative of the absorptive part of an elastic scattering amplitude exists in the interval t1≤t≤0, then, the total cross section has the asymptotic upper bound \({}_{\sigma T}(S) < s^{1/(N + 1)} \)
