Sensitivity and accuracy of Casimir force measurements in air
Joseph L. Garrett, David A. T. Somers, Kyle Sendgikoski +1
Quantum electrodynamic fluctuations cause an attractive force between metallic surfaces. At separations where the finite speed of light affects the interaction, it is called the Ca…
Effect of lateral tip motion on multifrequency atomic force microscopy
Joseph L. Garrett, Lisa J. Krayer, Kevin J. Palm +1
In atomic force microscopy (AFM), the angle relative to the vertical () that the tip apex of a cantilever moves is determined by the tilt of the probe holder and the geometr…
Mid-infrared time-resolved photoconduction in black phosphorus
Ryan J. Suess, Edward Leong, Joseph L. Garrett +5
Black phosphorus has attracted interest as a material for use in optoelectronic devices due to many favorable properties such as a high carrier mobility, field-effect, and a direct…
Fast, high-resolution surface potential measurements in air with heterodyne Kelvin probe force microscopy
Joseph L. Garrett, Jeremy N. Munday
Kelvin probe force microscopy (KPFM) adapts an atomic force microscope to measure electric potential on surfaces at nanometer length scales. Here we demonstrate that Heterodyne-KPF…
The effect of patch potentials in Casimir force measurements determined by heterodyne Kelvin probe force microscopy
Joseph L. Garrett, David Somers, Jeremy N. Munday
Measurements of the Casimir force require the elimination of electrostatic interactions between the surfaces. However, due to electrostatic patch potentials, the voltage required t…
