Analyzing absorption backgrounds in single-walled carbon nanotube spectra.
The sources of broad backgrounds in visible-near-IR absorption spectra of single-walled carbon nanotube (SWCNT) dispersions are studied through a series of controlled experiments. Chemical functionalization of nanotube sidewalls generates background absorption while broadening and red-shifting the resonant transitions. Extensive ultrasonic agitation induces a similar background component that m...
متن کاملSingle-Walled Carbon Nanotube Electronics
Single walled carbon nanotubes (SWNTs) have emerged as a very promising new class of electronic materials. The fabrication and electronic properties of devices based on individual SWNTs are reviewed. Both metallic and semiconducting SWNTs are found to possess electrical characteristics that compare favorably to the best electronic materials available. Manufacturability issues, however, remain a...
متن کاملSingle - Walled 14 . Single - Walled Carbon Nanotube Sensor Concepts
Carbon nanotubes are nanocomponents par excellence that offer unique properties to be exploited in next-generation devices. Sensing applications are perhaps the class that has most to gain from single-walled carbon nanotubes (SWNTs); virtually any property of SWNTs (e.g., electronic, electrical, mechanical, and optical) can result or has already resulted in sensor concept demonstrators. The bas...
متن کاملSingle-Walled Carbon Nanotube Network Gas Sensor
Gas sensors are generally defined as devices to detect or measure concentration of (bio-) chemicals in gaseous state. The demands of highly sensitive gas sensors for industry, environmental monitoring, safety, biomedicine, and pharmaceutics have provoked the intensive research interests in micro-electromechanical systems (MEMS) and nanotechnology. The nanotechnology in conjunction with MEMS has...
متن کاملFitting Single-Walled Carbon Nanotube Optical Spectra
In this work, a comprehensive methodology for the fitting of single-walled carbon nanotube absorption spectra is presented. Different approaches to background subtraction, choice of line profile, and calculation of full width at half-maximum are discussed both in the context of previous literature and the contemporary understanding of carbon nanotube photophysics. The fitting is improved by the...
