Analyzing Electronic Excitations and Exciton Binding Energies in Y6 Films

open access: yesAdvanced Functional Materials, EarlyView.
The Y6 molecule is used for increasing the efficiency of organic solar cells. The exciton binding energy is calculated for ensembles of Y6 molecules that are representative of the typically used films. The calculations show that the excitons typically spread out over many molecules.

High‐Performance Low‐Emissivity Paints Enabled by N‐Doped Poly(benzodifurandione) (n‐PBDF) for Energy‐Efficient Buildings

open access: yesAdvanced Functional Materials, EarlyView.
This study introduces a scalable and colored low‐emissivity (low‐e) paint achieved by spraying an ultrathin n‐doped poly(benzodifurandione) (n‐PBDF) coating onto various colored substrates. The low‐e paint enhances thermal regulation by reducing mid‐infrared thermal emissivity to 0.19, thereby stabilizing indoor temperatures across diverse climates ...

Losses of the parallel-plate dielectric resonator

open access: yesIET Microwaves, Antennas & Propagation, 2006
The various loss aspects of the parallel-plate microwave dielectric resonator for the TE 01delta mode is studied from a modified field model. The main merit of this field model is that it provides very simple electromagnetic field expressions of this field mode. Various methods of calculation of losses are discussed.

Enhanced Terahertz Spectroscopy of a Monolayer Transition Metal Dichalcogenide

open access: yesAdvanced Functional Materials, EarlyView.
An ad‐hoc engineered metallic surface is employed to perform enhanced terahertz spectroscopy of a monolayer transition metal dichalcogenide (TMD). Thanks to a local absorption boost of 104, this technique allows for the extraction of the phonon resonance features and effective permittivity of the 2D material, paving the way for the rational design of ...
