, 2017 This paper systematically develops the Schr\"odinger formalism that is valid also for gyrotropic media where the material weights $W = \left ( \begin{smallmatrix} \varepsilon & \chi \chi^* & \mu \end{smallmatrix} \right ) \neq \overline{W}$ are complex ...

Nonlinear interfaces: intrinsically nonparaxial regimes and effects [PDF]
, 2009 The behaviour of optical solitons at planar nonlinear boundaries is a problem rich in intrinsically nonparaxial regimes that cannot be fully addressed by theories based on the nonlinear Schrödinger equation.

A Heparin‐Functionalized Scaffold with HB‐EGF Immobilization for Tissue Engineering
Advanced Healthcare Materials, EarlyView.In this study, a heparin‐functionalized scaffold is designed for bio‐mimicking growth factors reservoir function of extracellular matrix. Due to the presence of heparin‐binding domain, heparin‐binding epidermal growth factor‐like growth factor (HB‐EGF) is effectively and spatially captured by heparin‐functionalized scaffold.

Effect of Host Anisotropy on Phosphorescent Emitter Orientation and Light Outcoupling in OLEDs
Advanced Optical Materials, EarlyView.The orientation of the emissive transition dipole moment of a cage‐type Iridium complex can be tuned by the anisotropic alignment of the cohost material, which is expressed as the S$S$ parameter of the film. Thus, the external quantum efficiency of OLEDs can be further enhanced to reach values above 30%.

Simulation of Carrier Injection Pathways in Axial GaN Nanowire MicroLEDs
Advanced Theory and Simulations, EarlyView.This study examines how geometrical variations in the active region affect carrier injection in multiple quantum well light‐emitting diodes (LEDs) based on axial nanowires. The key role of semipolar quantum wells located at the nanowire edges is highlighted, which efficiently facilitates electron injection into the central polar quantum wells.

A new exactly integrable hypergeometric potential for the Schr\"odinger equation
, 2018 We introduce a new exactly integrable potential for the Schr\"odinger equation for which the solution of the problem may be expressed in terms of the Gauss hypergeometric functions. This is a potential step with variable height and steepness.

Advanced Theory and Simulations, EarlyView.This article develops a variational formulation for modeling a silicon semiconductor through a multiwell approach utilizing phosphorus atoms as a dopant substance. The variational formulation here developed may be used to find an optimal phosphorus density distribution concerning an originally silicon density, in order to maximize the electrical ...

A reduced-order representation of the Schrödinger equation
AIP Advances, 2016 A reduced-order-based representation of the Schrödinger equation is investigated for electron wave functions in semiconductor nanostructures. In this representation, the Schrödinger equation is projected onto an eigenspace described by a small number of ...
