    “…We performed a combined secondary electron yield and x-ray photoelectron spectroscopy study on a prototypical system formed by increasing coverages of amorphous carbon (a-C) deposited on atomically clean Cu. A remarkably thin a-C layer, of about 6–8 nm, is surprisingly enough to lower below 1 the secondary emission yield of the whole system. …”
