1 Introduction to Laser Micro-to-Nano Manufacturing
51
Numerical innovative methods have been investigated for particle manipulation.
Microrobots have been proposed for manipulation [168]. It is facile to generate a
microbubble by laser heat and use this bubble as a microrobot for particle manipulation [169]. Recently, such a microrobot has been demonstrated to enable 3D
assembly of a micromechanical device [170]. Surface tension and LB methods are
also used for nanowire alignment [76]. Large-area photonic crystal can be formed
through self-assembly [171]. Laser-induced front transfer can be a powerful tool for
nanomaterial transporting and manipulation. The last chapter of this book will focus
on this method.
1.6 Nanojoining and Molecular Devices
1.6.1 Overview of Nanojoining
Welding of nanomaterials is essential manufacturing of functional nanoelectronics
[172], including nanocircuits [173], light-gated nanowire transistors [174], nano
waveguides and nanophotonic circuits and nanoplasmonic devices for quantum
computation [5, 89, 175]. To realize a nanoscale joining, various methods have been
developed to join nanomaterials, such as mechanical riveting [176, 177], mechanical pressure [178, 179], adhesive bonding [180, 181], cold welding [45, 47, 48],
Joule heating [182–185], thermal annealing [95, 186–188], soldering and brazing
[189–195], and laser (laser-induced plasmonic) welding [196–198].
