1. 1. Nonresonant high-frequency actuation of carbon based nanoelectromechanical oscillators

   Författare :Martin Eriksson; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; nanoelectromechanical oscillators; graphene; nonresonant; mechanical vibra- tions; selective mode actuation;

   Sammanfattning : Carbon based nanoelectromechanical oscillators outperform their predecessors in many ways. In particular, their extraordinarily high quality factors make them very promising for sensor applications. To operate the nano oscillators, different kinds of actuation mechanisms are utilised, for instance direct or parametric resonance. LÄS MER

3. 2. 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
