Introduction to responsive NANOTUBES-FIBERS: Intelligent Sensors Nelson Pinilla 1 Stevens Institute of Technology, Design and Manufacturing Institute (DMI), Castle Point on Hudson Hoboken, NJ 07030 Abstract On going research has established that single-walled nanotubes are suitable as electron field emitters, ambipolars, high electrical conductors and potential field-effect transistors. Assumptions of continuous media of a single nano-cylindrical tube (SWCNT) [1] formed by a “rolling up” from an infinite strip of graphite, that encloses linking interatomic potentials, and atomic bundles that incorporate metallic, or semiconducting electronic properties permit a switching mechanism like a Field Effect Transistor, (CNTFET) [2]. This paper is an introductory study for applications of ambipolar conduction of some CNT Field Effect Transistors, gate voltage at the surface traction. A mathematical boundary that has simulated transistors using semiclassical method based on the Schottky barrier (SB) field effect transistor mechanism [3] is presented. Keywords- Logic circuits, nanoelectronics, electron field emitters, field effect transistors, molecular electronics. 1. Introduction Our original goal is to develop of CNTFET switching mechanisms for the application of energy sensing on military equipment. In the track for this applicable work, we would have some developments through this introduction of responsive nanotubes, nanofibers as intelligent sensors. 1 E-mail address: nelson.pinilla@stevens.edu PhD Candidate, Department of Mechanical Engineering, Stevens Institute of Technology, Castle Point on Hudson, Hoboken, NJ 07030
