We report the field emission properties of two-dimensional SnSe nanosheets (NSs) and Au/SnSe nano-heterostructure (NHS) prepared by a simple and economical route of one-pot colloidal and sputtering ...

Graphene is one of the ideal nanomaterials to be paired with silicon and their complementary properties can be exploited in field emission (FE) devices. We reported an efficient way to produce and ...

In a proof-of-concept study published in Nature Physics, researchers drew magnetic squares in a nonmagnetic material with an electrified pen and then "read" this magnetic doodle with X-rays. The ...
