This 2-volume set addresses the most recent research progress on three-dimensional (3D) micro- and nano-technologies. Volume one gives in-depth knowledge on the novel physical properties of 3D structures and 3D micro- and nano-fabrication process, including 3D assembly, 3D printing, stereolithography and multiphoton lithography. Volume two introduces various micro- and nanoscale 3D devices such as 3D electronic sensors, optoelectronic devices, transistors, photovoltaics and microfluidics.
