Measurements of the alpha particle induced current in metal foils
… The measurements were made with a commercial Keithley picoammeter and with a custom built high precision current integrator. Measurements were made at pressures between 1 mTorr and atmosphere. At higher pressures, above 1 Torr, the measured current was greatly exceeded by the predicted …

Microfabrication and electrical characterization of lead-free sodium potassium niobate thin film ribbons on conformal substrates
… and characterized electrically using the Keithley Semiconductor Parameter Analyzer. In this initial experimental evaluation, it was found that at the frequency of 100 KHz, the dielectric constant of the KNN on PDMS is the highest at 427 followed by the Kapton at 410. The Ecoflex and …

The Interplay of Spin, Charge, and Heat: From Metal/Insulator Heterostructures to Perovskite Bilayers
… conductance and delta mode of a paired Keithley 6221/2182a for non-local resistance measurements can lead to false indicators of spin transport. Next, we turn out attention to a thickness dependent study in thermally-evaporated chromium (Cr) thin films on a bulk polycrystalline …

LAYER BY LAYER NANOASSEMBLY OF COPPER INDIUM GALLIUM SELENIUM (CIGS) NANOPARTICLES FOR SOLAR CELL APPLICATION
… were carried out for each of the films using the Keithley semiconductor characterization instruments and micromanipulator probing station. It was observed that the conductivity of the films was increased with the deposition of each additional layer. The I/V characteristics were also measured under …
