Mechanism of hydrogen, oxygen and humidity sensing by Cu/Pd-porous silicon–silicon structures

Nanocrystalline Porous Silicon

“…V.G. Litovchenko and co workers (Litovchenko et al, 2004) studied the mechanism of hydrogen, oxygen and humidity sensing using Cu-Pd/PS/Si structures. They coated polymer film on the PS surface and studied the chemisorptions of the gas molecules.…”
