Electro-deposited PdNi-Si Schottky barrier hydrogen sensors with improved time response
Electro-deposited PdNi-Si Schottky barrier hydrogen sensors with improved time response
In this paper, we present a method to speed up the response time through growth of a gradient in PdNi concentration with depth. we are able to create various Schottky barrier structures. Structure A has uniform concentration, structure B has an increased Pd concentration at the top surface to speed up H2 dissociation and structure C has as well an increased Ni concentration at the Si interface to improve the interface dynamics.

Abstract
In this paper, we present a method to speed up the response time through growth of a gradient in PdNi concentration with depth. we are able to create various Schottky barrier structures. Structure A has uniform concentration, structure B has an increased Pd concentration at the top surface to speed up H2 dissociation and structure C has as well an increased Ni concentration at the Si interface to improve the interface dynamics.
