1. 1. Toward Carbon based NEMS

   Författare :Farzan Alavian Ghavanini; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; carbon nanotubes CNT ; Nanoelectromechanical systems; and CMOS compatibility ; CNT-based switch; vertically aligned carbon nanofibers VACNF ; NEMS;

   Sammanfattning : A systematic analysis and assessment of carbon nanotube (CNT) based NEMS switches is presented and their features are compared to typical complementary metal-oxide-semiconductor (CMOS) performance parameters. It is shown that CNT-based switches with considerably smaller leakage current compared to CMOS switches can be realized. LÄS MER

3. 2. Electromechanical Instability in Suspended Nanowire-Based NEMS

   Författare :Fabio Santandrea; Göteborgs universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NEMS; Shuttle instability; Coulomb blockade; Carbon Nanotubes; Electronic Transport; Nonlinear Dynamics;

   Sammanfattning : "Nanoelectromechanical systems'' (NEMS) are a class of nanometer-sized mechanical structures coupled to electronic device of comparable dimensions. Their peculiar features make them interesting both from the technological and fundamental research viewpoints. LÄS MER

4. 3. There's Plenty of Room in Higher Dimensions - Nonlinear Dynamics of Nanoelectromechanical Systems

   Författare :Martin Eriksson; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; nonresonant actuation; quantum dots; NEMS; internal resonance; superconductivity; nonlinear dynamics;

   Sammanfattning : Nanoelectromechanical systems (NEMS) couple the dynamics of electrons to vibrating nanostructures such as suspended beams or membranes. These resonators can be used in for instance nanoelectronics and sensor applications. NEMS are also of fundamental interest since electrons exhibit strong quantum effects when confined in nanoobjects. LÄS MER

5. 4. Modelling of Molecular-Scale Nanoelectromechanical Systems

   Författare :Caroline Huldt; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; shuttle; mesoscopic; NEMS; graphene; multiscale; DFTB; DFT;

   Sammanfattning : Nanoelectromechanical systems (NEMS) couple electronic and mechanical degrees of freedom in a nanoscopic structure. The small size introduces many atomistic and quantum mechanical features which on the one hand open up for interesting new features and possibilities but on the other hand make it very difficult to formulate quantitative predictions.

7. 5. Integration and Fabrication Techniques for 3D Micro- and Nanodevices

   Författare :Andreas C. Fischer; Frank Niklaus; Karl F. Böhringer; KTH; []
   Nyckelord :Microelectromechanical systems; MEMS; Nanoelectromechanical systems; NEMS; silicon; wafer-level; chip-level; through silicon via; TSV; packaging; 3D packaging; vacuum packaging; liquid encapsulation; integration; heterogeneous integration; wafer bonding; microactuators; shape memory alloy; SMA; wire bonding; magnetic assembly; self-assembly; 3D; 3D printing; focused ion beam; FIB;

   Sammanfattning : The development of micro and nano-electromechanical systems (MEMS and NEMS) with entirely new or improved functionalities is typically based on novel or improved designs, materials and fabrication methods. However, today’s micro- and nano-fabrication is restrained by manufacturing paradigms that have been established by the integrated circuit (IC) industry over the past few decades. LÄS MER
