hi, every body:
I am a newbie here.
The surface morphology of a thin film will be analysed. But why "For the SEM analyses, TiO2 film was coated with a 10 nm gold–palladium (Au–Pd) layer by using polaron scanning electron microscopy (SEM) sputter coating unit E- 2500, before taking image."
can anybody tell me we needed to coat the 10nm layer of gold-palladium film?

To let the object conduct electricity?
I've often heard of coating objects for SEM.
Even if the object isn't broken by the accumulated charges, a buildup of electric potential would deflect the electron beam and distort the image. Is this an explanation?
