Plasmonically enhanced spectrally selective narrowband MWIR and LWIR light detection based on hybrid nanopatterned graphene and phase changing vanadium oxide heterostructure operating close to room temperature
Muhammad Waqas Shabbir, Sayan Chandra, Michael N. Leuenberger
We present the model of an ultrasensitive mid-infrared (mid-IR) photodetector operating in the mid-wavelength infrared (MWIR) and long-wavelength infrared (LWIR) domains consisting…
Wide Angle Dynamically Tunable Enhanced Infrared Absorption on Large Area Nanopatterned Graphene
Alireza Safaei, Sayan Chandra, Michael N. Leuenberger +1
Enhancing light-matter interaction by exciting Dirac plasmons on nanopatterned monolayer graphene is an efficient route to achieve high infrared absorption. Here, we designed and f…
Exchange Bias Effects in Iron Oxide-Based Nanoparticle Systems
Manh-Huong Phan, Javier Alonso, Hafsa Khurshid +7
The exploration of exchange bias (EB) on the nanoscale provides a novel approach to improving the anisotropic properties of magnetic nanoparticles for prospective applications in n…
Exchange Bias Effect in Au-Fe3O4 Nanocomposites
Sayan Chandra, N. A. Frey Huls, M. H. Phan +7
We report exchange bias (EB) effect in the Au-Fe3O4 composite nanoparticle system, where one or more Fe3O4 nanoparticles are attached to an Au seed particle forming dimer and clust…
Growth and physical property study of single nanowire (diameter ~ 45nm) of half doped Manganite
Subarna Datta, Sayan Chandra, Sudeshna Samanta +3
We report here the growth and characterization of functional oxide nanowire of hole doped manganite of La0.5Sr0.5MnO3 (LSMO). We also report four probe electrical resistance measur…
