Abstract: Graphene and flat gold have both been argued to enhance Raman scattering of molecular adsorbates through a chemical mechanism. Here we show that these two effects can add to each other. For Cu-phthalocyanine in between… read more here.

DOI: 10.1103/physrevlett.120.177702
Abstract: We report the experimental observation of strongly enhanced tunneling between graphene bilayers through a WSe_{2} barrier when the graphene bilayers are populated with carriers of opposite polarity and equal density. The enhanced tunneling increases sharply… read more here.

DOI: 10.1109/tmtt.2018.2791942
Abstract: Limited sensitivity and sensing range are arguably the greatest challenges in microwave sensor design. Recent attempts to improve these properties have relied on metamaterial (MTM)-inspired open-loop resonators coupled to transmission lines (TLs). Although the strongly… read more here.

DOI: 10.1126/sciadv.abe4206
Abstract: Sandwiching a ferroelectric between two paraelectrics squeezes out larger photovoltaic current. Ever since the first observation of a photovoltaic effect in ferroelectric BaTiO3, studies have been devoted to analyze this effect, but only a few… read more here.
