Time-Resolved Single Dopant Charge Dynamics in Silicon

Mohammad Rashidi, Jacob Burgess, Marco Taucer +4

As the ultimate miniaturization of semiconductor devices approaches, it is imperative that the effects of single dopants be clarified. Beyond providing insight into functions and l…

Superfluidity of 4He nanoclusters in confinement

Massimo Boninsegni

Structure and superfluid response of nanoscale size helium-four clusters enclosed in spherical cavities are studied by computer simulations. The curved surface causes the formation…

Dimensional Effects on the Density of States in Systems with Quasi-Relativistic Dispersion Relations and Potential Wells

A. Pokraka, R. Dick

Motivated by the recent discoveries of materials with quasi-relativistic dispersion relations, we determine densities of states in materials with low dimensional substructures and…

Optomechanics and thermometry of cryogenic silica microresonators

A. J. R. MacDonald, B. D. Hauer, X. Rojas +3

We present measurements of silica optomechanical resonators, known as bottle resonators, passively cooled in a cryogenic environment. These devices possess a suite of properties th…

New fabrication technique for highly sensitive qPlus sensor with well-defined spring constant

Hatem Labidi, Martin Kupsta, Taleana Huff +5

A new technique for the fabrication of highly sensitive qPlus sensor for atomic force microscopy (AFM) is described. Focused ion beam was used to cut then weld onto a bare quartz t…

Superfluid response of two-dimensional parahydrogen clusters in confinement

Saheed Idowu, Massimo Boninsegni

We study by computer simulations the effect of confinement on the superfluid properties of small two-dimensional (2D) parahydrogen clusters. For clusters of fewer than twenty molec…

Scanning tunneling spectroscopy reveals a silicon dangling bond charge state transition

Hatem Labidi, Marco Taucer, Mohammad Rashidi +6

We report the study of single dangling bonds (DB) on the hydrogen terminated silicon (100) surface using a low temperature scanning tunneling microscope (LT-STM). By investigating…

Nonlinear Power Spectral Densities for the Harmonic Oscillator

B. D. Hauer, J. Maciejko, J. P. Davis

In this paper, we discuss a general procedure by which nonlinear power spectral densities (PSDs) of the harmonic oscillator can be calculated in both the quantum and classical regi…

Time-Resolved Mass Sensing of a Molecular Adsorbate Nonuniformly Distributed Along a Nanomechnical String

T. S. Biswas, Jin Xu, N. Miriyala +4

We show that the particular distribution of mass deposited on the surface of a nanomechanical resonator can be estimated by tracking the evolution of the device's resonance frequen…
