Journal ArticleDOI
Scanning plasmon optical microscope
Y. K. Kim,P. M. Lundquist,J. A. Helfrich,J. M. Mikrut,George K. Wong,P. R. Auvil,John B Ketterson +6 more
TL;DR: In this article, a new scanning near field optical microscopy based on surface plasmon resonance is presented, where enhanced fields are localized at individual surface irregularities by the scattering of plasmons and the scattered plasms produce a conical radiation.
Journal ArticleDOI
Centro‐symmetric technique for measuring shear modulus, viscosity, and surface tension of spread monolayers
TL;DR: In this paper, a Teflon cup 12.7 cm (5.4 in) in inner diameter with sloping interior sides is used to measure the shear modulus, the viscosity, and the surface pressure of a monomolecular film on water under a hydrostatic compression.
Journal ArticleDOI
Thermoelectric power of MBE grown Bi thin films and BI/CDTE superlattices on CdTe substrates
TL;DR: In this paper, the authors measured the thermoelectric power (TEP) of epitaxial Bi thin films and Bi/CdTe superlattices grown on CdTe substrates as a function of temperature in the range 20-300 K.
Journal ArticleDOI
Ferromagnetic Resonance of a YIG film in the Low Frequency Regime
Seongjae Lee,Scott Grudichak,Joseph Sklenar,C. C. Tsai,Moongyu Jang,Qinghui Yang,Huaiwu Zhang,John B Ketterson +7 more
TL;DR: In this paper, an improved method for characterizing the magnetic anisotropy of films with cubic symmetry is described and applied to an yttrium iron garnet (111) film.
Journal ArticleDOI
Slow thermal equilibration in methylammonium lead iodide revealed by transient mid-infrared spectroscopy.
Peijun Guo,Jue Gong,Sridhar Sadasivam,Yi Xia,Tze-Bin Song,Benjamin T. Diroll,Constantinos C. Stoumpos,John B Ketterson,Mercouri G. Kanatzidis,Maria K. Y. Chan,Pierre Darancet,Tao Xu,Richard D. Schaller,Richard D. Schaller +13 more
TL;DR: The authors use a spectroscopic approach to observe unusually slow thermal equilibration between the organic and inorganic components and offer insights into thermal transport and heat management of the emergent hybrid material class.
