Bandgap‐Engineered AlGaAs/GaAs Heterostructures for Wavelength‐Selective Dual‐Polarity Photoelectrochemistry

Advanced Functional Materials, EarlyView.
Bandgap‐engineered AlGaAs/GaAs heterostructures exhibit wavelength‐selective dual‐polarity photoelectrochemistry, switching from photocathodic to photoanodic response depending on excitation wavelength. The polarity transition is governed by band‐selective absorption, built‐in electric‐field‐driven carrier transport, and interfacial charge‐transfer ...
