Photo-capacitance response of internal tunnelling coupling in quantum-dot-imbedded heterostructures under selective photo-excitation

, 2004
Under selective photo-excitation, the capacitance response of internal tunnelling coupling in quantum-dots-imbedded heterostructures is studied to clarify the electronic states and the number densities of electrons filling in the quantum dots (QDs).

Unveiling a Near‐Total Rear Passivation for High Performance of Ultra‐Thin ACIGS

Advanced Science, EarlyView.
Ultra‐thin solar cells of (Ag,Cu)(In,Ga)Se2 (ACIGS) suffer from rear interface recombination, limiting their performance. To tackle it, a full coverage plasma enhanced chemically vapor‐deposited 8 nm porous SiOx passivation layer was implemented and evaluated. It is shown that a combination of the near‐complete passivation from silica and the formation

Correlated Polymer‐Proton Hopping Enables Water‐Independent Fast Proton Transport in Poly(Ionic Liquid) Membranes

Advanced Science, EarlyView.
A polymer chain in motion: backbone, ring, and counterion dynamics interlock across timescales to relay protons through poly(ionic liquid) membranes. ABSTRACT Polymer electrolyte membranes composed of ionic liquids (IL), capable of conducting protons efficiently at elevated temperatures, without external humidification, could transform fuel cell ...

Nickel Intercalation in Epitaxial Graphene on SiC(0001): A Novel Platform for Engineering Two‐Dimensional Heterostructures

Advanced Science, EarlyView.
Ni‐intercalated graphene on SiC is achieved through a scalable colloidal nanoparticle deposition route. 2D heterostructures show preserved graphene band structure, stable under ambient conditions, and robust interfacial magnetism. Intercalated 2D Ni represents a promising candidate for next‐generation spintronic devices and is a scalable pathway to ...

Structural Changes and Transport Properties of YBa2Cu3O7 Locally Modified by a He+ Focused Ion Beam

Advanced Science, EarlyView.
The structure and the electric transport properties of YBa2Cu3O7 modified with 30 keV He+${\rm He}^{+}$ ions depend on the irradiation dose and lateral size of the irradiated area, as shown by low‐temperature resistivity measurements, diffraction with a nanofocused X‐ray beam and atomic force microscopy.
