Inadequacy of the Mott-Schottky equation in strongly pinned double Schottky barriers with no deep donors [PDF]

, 2012
The capacitive behaviour of an intergranular double Schottky barrier in a polycrystalline semiconductor was evaluated. We found that the widely applied version of the Mott-Schottky equation can lead to significant errors.

Spontaneously Formed Mott‐Schottky Electrocatalyst for Lithium‐Sulfur Batteries

Advanced Materials Interfaces, 2020
AbstractDeveloping effective electrocatalyst and deciphering its mechanism in modulating sulfur‐species‐conversion is still an important but challenging part for lithium sulfur (Li‐S) batteries. Here, a “spontaneous formed” strategy is presented to construct hierarchical CNT@ surface oxidized TiN nanoparticles (CNT@TiON) and the detailed interfaces ...
