Integrated Electronic Transport and Thermometry at milliKelvin Temperatures and in Strong Magnetic Fields [PDF]

open access: yes, 2011
We fabricated a He-3 immersion cell for transport measurements of semiconductor nanostructures at ultra low temperatures and in strong magnetic fields. We have a new scheme of field-independent thermometry based on quartz tuning fork Helium-3 viscometry ...

Application of the equipartition theorem to the thermal excitation of quartz tuning forks [PDF]

open access: yes, 2011
The deflection signal of a thermally excited force sensor of an atomic force microscope can be analyzed to gain important information about the detector noise and about the validity of the equipartion theorem of thermodynamics.

Quartz Tuning Fork as Humidity Sensor

open access: yesJournal of Nanomedicine & Nanotechnology, 2017
This paper highlight, a novel and simple solution growth method to develop the deposition of nanocrystalline ZnO films on QTF to act as sensor, integrating merits of both SILAR and CBD techniques. The obtained film is characterized by high deposition rate, high film and used for the humidity sensing.

Calibration of quartz tuning fork spring constants for non-contact atomic force microscopy: direct mechanical measurements and simulations

open access: yesBeilstein Journal of Nanotechnology, 2014
Quartz tuning forks are being increasingly employed as sensors in non-contact atomic force microscopy especially in the “qPlus” design. In this study a new and easily applicable setup has been used to determine the static spring constant at several ...

Fluid Sensing Using Quartz Tuning Forks—Measurement Technology and Applications

open access: yesSensors, 2019
We provide an overview of recent achievements using quartz tuning forks for sensing liquid viscosity and density. The benefits of using quartz crystal tuning forks (QTFs) over other sensors are discussed on the basis of physical arguments and issues arising in real world applications.

Radiometric Constraints on the Timing, Tempo, and Effects of Large Igneous Province Emplacement

open access: yesGeophysical Monograph Series, Page 27-82., 2021

Exploring the links between Large Igneous Provinces and dramatic environmental impact

An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.

Spring constant of a tuning-fork sensor for dynamic force microscopy

open access: yesBeilstein Journal of Nanotechnology, 2012
We present an overview of experimental and numerical methods to determine the spring constant of a quartz tuning fork in qPlus configuration. The simple calculation for a rectangular cantilever is compared to the values obtained by the analysis of the ...

Influence of Air Pressure on the Resonance Properties of a T-Shaped Quartz Tuning Fork Coupled with Resonator Tubes

open access: yesApplied Sciences, 2021
A theoretical analysis and experimental investigation of the influence of gas pressure on resonance properties, namely, the quality factor and resonance frequency, of a T-shaped quartz tuning fork (QTF) is reported here. Two configurations are considered:

Controlling the quality factor of a tuning-fork resonance between 9 K and 300 K for scanning-probe microscopy [PDF]

open access: yes, 2011
We study the dynamic response of a mechanical quartz tuning fork in the temperature range from 9 K to 300 K. Since the quality factor Q of the resonance strongly depends on temperature, we implement a procedure to control the quality factor of the ...
