2. 1. Electromechanical Interactions in Shuttle Systems and Carbon Nanotube Relays

   Author : Tomas Nord; Chalmers tekniska högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Coulomb blockade; carbon nanotubes; memory device; nanorelay; single electron tunneling; van der Waals forces; NEMS; shuttle transport; mesoscopic; nanoelectromechanical systems;

   Abstract : In this thesis we theoretically investigate two kinds of nanoscale systems where there is a strong electromechanical coupling, i.e. an intricate relation between the Coulomb forces that can appear in these systems and the displacements of parts of the systems that they cause.

4. 2. Carbon-nanotube-based nanoelectromechanics

   Author : Magnus Jonsson; Chalmers tekniska högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; electromechanical instabilities; multi-mode excitations; NEMS; suspended carbonnanotubes; Nanoelectromechanicalsystems; non-linearresonances; nanorelay; carbon nanotubes; surface forces;

   Abstract : Carbon nanotubes, a novel material with extraordinary mechanical and electrical properties, are good candidates for designing nanoelectromechanical systems. The typical length scale of these systems is nanometers and an important characteristic is a coupling between electrical and mechanical degrees of freedom. READ MORE

   Abstract : Films of aligned multi-walled carbon nanotubes (MWCNTs) areinteresting for applications such as cold emission cathodes in flat-panel display technology and in lighting elements. MWCNTs are, besides this, good candidates to be used innanoelectromechanical systems (NEMS). READ MORE

7. 5. Towards the Integration of Carbon nanostructures into CMOS technology

   Author : Mohammad Kabir; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; transmission electron microscopy TEM .; chemical vapour deposition CVD ; electron beam lithography EBL ; carbon nanotube CNT ; silicidation; atomic force microscopy AFM ; carbon nanofiber CNF ; Complementary metal oxide semiconductor CMOS ; dc-glow discharge plasma; growth mechanism; metal catalyst; scanning electron microscopy SEM ;

   Abstract : Relentless efforts for miniaturization of traditional complementary metal oxide semiconductor (CMOS) devices have reached the limit where the device characteristics are governed by quantum phenomena which are difficult to control. This engendered a need for finding alternative new materials that can be engineered to fabricate devices that will possess at least the same or even better performance than existing CMOS devices.
