Localized microwave resonances in strained SrTiO3 thin films
Patrick Irvin, J. H. Haeni, Darrell G. Schlom +1
The frequency-dependent polar dynamics of strained SrTiO3 films grown on DyScO3 are investigated using time-resolved confocal scanning optical microscopy. Microwave frequency elect…
Development and Performance of the Nanoworkbench: A Four Tip STM for Electrical Conductivity Measurements Down to Sub-micrometer Scales
Olivier Guise, Hubertus Marbach, Moon-Chul Jung +3
A multiple-tip ultra-high vacuum (UHV) scanning tunneling microscope (MT-STM) with a scanning electron microscope (SEM) for imaging and molecular-beam epitaxy growth capabilities h…
Three-dimensional polarization imaging of (Ba,Sr)TiO3:MgO composites
Patrick Irvin, Ruyan Guo, Amar Bhalla +1
The dielectric tuning and loss of (Ba,Sr)TiO3:MgO bulk composites depend strongly on the connectivity and interaction among the two phases. To investigate this relationship, the po…
320-Channel Dual Phase Lock-in Optical Spectrometer
P. S. Fodor, S. Rothenberger, J. Levy
The development of a multiple-channel lock-in optical spectrometer (LIOS) is presented, which enables parallel phase-sensitive detection at the output of an optical spectrometer. T…
Formation and Thermal Stability of sub-10 nm Carbon Templates on Si(100)
Olivier Guise, Joachim Ahner, John T. Yates +1
We report a lithographic process for creating high-resolution (<10 nm) carbon templates on Si(100). A scanning electron microscope, operating under low vacuum (10E-6 mbar), produce…
Variable - temperature scanning optical and force microscope
P. S. Fodor, H. Zhu, N. G. Patil +1
The implementation of a scanning microscope capable of working in confocal, atomic force and apertureless near field configurations is presented. The microscope is designed to oper…
