Optimization of Temperature Programmed Sensing for Gas Identification Using Micro-Hotplate Sensors

November 26, 1998

Author(s)

T A. Kunt, T. J. McAvoy, Richard E. Cavicchi, Stephen Semancik

Micro-hotplate chemical gas sensors, such as those being developed at the National Institute of Standards and Technology [NIST] by micromaching SI, can be operated in a temperature-pulsed mode, due to their small size and mass. In this paper, a new

Doping Effects and Reversibility Studies on Gas-Exposed (Alpha)-Sexithiophene Thin Films

September 1, 1998

Author(s)

C Kendrick, Stephen Semancik

The electronic effects produced by controlled gas exposures on [alpha]-sexithiophene thin films have been investigated using x-ray photoelectron spectroscopy (Incremental exposures of [alpha]6T to NO 2, O 2, NH 3 in N 2, and water vapor in N 2 were

Kinetically-Controlled Chemical Sensing Using Micromachined Structures

May 1, 1998

Author(s)

Stephen Semancik, Richard E. Cavicchi

Microdevices produced by machining silicon can offer a variety of control functionality on a miniature scale, 1.2 with general advantages connected to not only reduced size (less invasive), but also lower power requirements, lower cost, and reproducibility

Time-Dependent Conductance of Pd-Dosed SnO2 (110)

January 1, 1998

Author(s)

Richard E. Cavicchi, V Sukharev, Stephen Semancik

Time-dependent phenomena related to the reaction of ultrathin films of Pd deposited on SnO2 (110) surfaces of differing oxygen content have been investigated. Conductance measurements and x-ray photoemission spectroscopy (XPS) were used to characterize
