Precise determination of reliable work function in according to the definition from photoelectric effect [PDF]

arXiv, 2017
The strategy of using the definition of work function from photoelectric effect to determine precise and reliable work function by the contribution of frequency to photoelectric yield is investigated theoretically in this paper. Based on the Fermi-Dirac distribution and the definition of work function proposed by Einstein in photoelectric effect, a ...

Ultrafast Room‐Temperature Nanofabrication via Ozone‐Based Gas‐Phase Metal‐Assisted Chemical Etching for High‐Performance Silicon Photodetectors

Advanced Functional Materials, EarlyView.
Ozone‐based gas‐phase metal‐assisted chemical etching enables unprecedented room‐temperature fabrication of high‐quality silicon nanowires. The superior oxidation potential of O3 drives rapid vertical etching (1 µm min−1) while maintaining exceptional structural integrity. The pristine nanowire surfaces enable high‐performance core‐shell photodetectors

Understanding and Addressing the Performance Asymmetry Issue in Semitransparent Laminated Organic Photovoltaic Devices

Advanced Functional Materials, EarlyView.
This work addresses the challenge of current–voltage asymmetry in scalable laminated semitransparent organic photovoltaics (OPVs) for indoor applications. Vertical stratification of materials is shown to create an energy barrier, leading to performance differences under different illumination directions.

The Van der Waals interactions and the photoelectric effect in noncommutative quantum mechanics [PDF]

Published in Chin. Phys. Lett., Volume 24, Number 5, (2007), 1183, 2005
We calculate the long-range Vanderwaals force and the photoelectric cross section in a \nc set up. While we argue that non-commutativity effects could not be discerned for the Vanderwaals interactions, the result for the photoelectric effect shows deviation from the usual commutative one, which in principle can be used to put bounds on the space-space ...

Rapid Surface Reconstruction of In2S3 Photoanode via Flame Treatment for Enhanced Photoelectrochemical Performance

Advanced Materials, EarlyView.
A rapid surface reconstruction strategy is proposed to enhance the charge collection efficiency and stability of indium sulfide (In2S3) photoanode via a high‐temperature flame treatment. This method selectively transforms the In2S3 surface into a diffusionless In2O3 and generates bulk sulfur vacancies, resulting in surface‐reconstructed In2S3 (sr‐In2S3)
