摘　　要：Micro/nanoelectromechanical systems(MEMS/NEMS)have potential applications in sensing,cooling,and mechanical signal processing.Thanks to the development of modern MEMS fabrication techniques,in analogy to photons,phonons in NEMS attract significant research interests recently.Single-electron tunneling events in quantum-dot-like nanostructures have been widely used in mesoscopic transport studies.Quantum dots are also considered as an ideal candidate platform for solid-state quantum computation.The coupling of these two types of systems has vast application prospects in information storage,transfer and also fundamental physics investigations.The most popular system realizing such coupling is a suspended carbon nanotube,in which the local gates can be used to confine a quantum dot,actuate a resonator and tune the resonant frequency.In this review,we focus on recent progress in this coupled system composed of carbon-based materials and discuss device fabrication,coupling mechanisms,and applications.Micro/nanoelectromechanical systems（MEMS/NEMS）have potential applications in sensing,cooling,and mechanical signal processing.Thanks to the development of modern MEMS fabrication techniques,in analogy to photons,phonons in NEMS attract significant research interests recently.Single-electron tunneling events in quantum-dot-like nanostructures have been widely used in mesoscopic transport studies.Quantum dots are also considered as an ideal candidate platform for solid-state quantum computation.The coupling of these two types of systems has vast application prospects in information storage,transfer and also fundamental physics investigations.The most popular system realizing such coupling is a suspended carbon nanotube,in which the local gates can be used to confine a quantum dot,actuate a resonator and tune the resonant frequency.In this review,we focus on recent progress in this coupled system composed of carbon-based materials and discuss device fabrication,coupling mechanisms,and applications.
