Single-Crystal Organic Charge-Transfer Interfaces probed using Schottky-Gated Heterostructures

open access: yes, 2012
Organic semiconductors based on small conjugated molecules generally behave as insulators when undoped, but the hetero-interfaces of two such materials can show electrical conductivity as large as in a metal.

SKPFM study of hydrogen in a two phase material. Experiments and modelling

open access: yesInternational Journal of Hydrogen Energy, 2019
Abstract Scanning Kelvin Probe Force Microscopy (SKPFM) was used to study hydrogen diffusion in a duplex stainless steel. The experiments were conducted on specimens covered with a nanometric palladium layer and pre-charged with hydrogen. A finite element model (FEM) of hydrogen diffusion in a three phase system (ferrite, austenite and palladium) was

Interfacial Dipole Engineering With Taurine‐Modified SnO2 Electron Transport Layer for Efficient and Stable Perovskite Solar Cells

open access: yesRare Metals, EarlyView.
ABSTRACT Organic‐inorganic metal halide perovskite solar cells (PSCs) are promising for photovoltaics due to their excellent optoelectronic properties. However, achieving high efficiency and stability remains challenging, mainly due to defects and energy losses at the electron transport layer (ETL)/perovskite interface.
