Preface
Manufacturing is the basis of modern economics and society. The modern pursuit
of high quality of life requires the revolution of modern manufacturing and engineering to produce products with unprecedented complex structures and properties.
Reducing the costs in materials and energy, and enhancing freedom in design while
continuously improving the performance at the device and system level remain
major technological challenges. Micro- and nano-manufacturing, especially 2D and
3D microprinting, has emerged as effective solutions for the development of the
Internet of things (IoTs), 5G/6G communication, portable electronics, artificial
intelligence, and automated driving.
Lasers are powerful tools for various machining processes. For precision
manufacturing at a micro-to-nano-scale, the fundamental understanding of lightnanomaterial interaction is crucial. The basic energy and mass transporting govern
the relevant machining procedures. Unlike the macroworld, the unique properties
and principles will be dominant in a microworld and nanoworld, such as the surface
energy becomes dominant compared to volume energy and capillary force will
overcome the gravitational force. This leads to the size effect of melting and
innovative assembly strategy of nanomaterials. These must be further considered in
precision micro-to-nano-manufacturing. On the other hand, with the blooming of
laser technologies, laser enables work using tunable wavelengths, pulses, shapes,
powers and other processing parameters. Especially due to the extensive availability
of cheaper semiconductor laser and fiber laser, laser-based manufacturing becomes
versatile in 2D-3D printing. Moreover, laser-based micro-nano-manufacturing can
be integrated with other advanced manufacturing tools to address intellectual and
green manufacturing. This makes laser-based micro-nano-manufacturing very
unique and promising for microelectronics, energy, environment application.
In this book, we first introduce the fundamental of light-nanomaterial interaction,
the size effect, the scaling of nanomaterials, and the surface plasmonic excitation of
nanomaterials. For photonic manufacturing, we mainly compare the photothermal
effect induced by long pules (long than 1 picosecond) or continue wave laser to the
nonthermal effect induced by an ultrafast pulsed laser (shorter than 1 picosecond).
