Abstract: Abstract We exploit the concept of critical coupling to graphene based chip-integrated applications and numerically demonstrate that a perfect absorption (PA) absorber in the near-infrared can be obtained by graphene/Al2O3 multilayer stack (GAMS) critical coupling… read more here.

Abstract: In this work, TiN/Ti(C,N)/Al2O3 multilayer coatings were deposited using an industrial-scale thermal CVD system. Two polymorphs of Al2O3, the stable α- and the metastable κ-Al2O3, were obtained by the deposition of specific bonding layers at… read more here.
