NbN Broadband Plasmonic Absorbers for Efficient Hot‐Carrier Injection Toward Improved Solar‐to‐Hydrogen Conversion

open access: yesAdvanced Science, EarlyView.
Niobium nitride (NbN) broadband plasmonic metasurface absorbers provide an efficient platform for solar‐energy conversion through hot‐carrier injection. Quasi‐epitaxial NbN features a low work function of 4.0 eV, reducing the interfacial injection barrier and facilitating charge transfer into adjacent photocatalysts.

Surface photo-response of nanostructure metal oxides using high vacuum kelvin probe technique

open access: yes, 2011
The Kelvin Probe (KP) is a non-contact, non-destructive vibrating capacitor device used to measure the work function difference, or for non-metals, the surface potential, between a conducting specimen and a vibrating tip.

Achieving High‐Instantaneous Pulse Power in Contact‐Separation TENG via Series Capacitive Voltage Control Architecture

open access: yesAdvanced Science, EarlyView.
Conventional contact‐separation triboelectric nanogenerators generate high voltage but deliver limited power due to premature charge dissipation. Here, a capacitive charge reservoir architecture decouples charge accumulation from discharge triggering, enabling sequential voltage amplification via floating‐layer capacitive coupling.

Use of Scanning Kelvin Probe to Study the Corrosion Protection of HDG by Chromating Coating

open access: yes, 2001
In this study the influence of chromating on the corrosion resistance of zinc coating is investigated with the scanning Kelvin probe technique (SKP). Two different treatments were used: a classical industrial solution, i.e.

Pressure‐Tuned Superconducting Dome and Persistent Charge‐Density‐Wave Order in NdSeTe2

open access: yesAdvanced Science, EarlyView.
NdSeTe2 exhibits an unusual pressure‐tuned phase diagram in which charge‐density‐wave order does not disappear at optimal superconductivity. Instead, Raman spectroscopy reveals a transformation from long‐range to short‐range correlations that remain invisible to resistivity and persist across the entire superconducting dome.

Electron‐Beam Enables Spatially Resolved Defect‐Mediated Work Function Modulation in FAPbI3 Perovskite Thin Films

open access: yesAdvanced Science, EarlyView.
Electron‐beam irradiation enables defect‐mediated work function modulation in metal halide perovskites by regulating interstitial iodides. This approach allows continuous Fermi‐level tuning and spatially resolved formation of lateral surface‐potential‐defined junctions with built‐in potential.
