Disorder dominated microwave conductance spectra of doped silicon nanowire arrays.

Conductance spectra of doped silicon nanowire (SiNW) arrays were measured from 0.5 to 50 GHz at temperatures between 4 and 293 K. For arrays consisting of 11 to >10(4) SiNWs, the conductance was found to increase with frequency as f(s), with 0.

Complementary planar terahertz metamaterials.

Planar electric split ring resonator (eSRR) metamaterials and their corresponding inverse structures are designed and characterized computationally and experimentally utilizing finite element modeling and THz time domain spectroscopy. A complementary response is observed in transmission. Specifically, for the eSRRs a decrease in transmission is observed at resonance whereas the inverse structures display an increase in transmission.
