This book provides the basic theory, method framework and application results of urban metabolism. Urban metabolism is an important research philosophy and approach for analyzing urban mega organism and its ecological environmental problems. It has constantly formed quantitative network research framework and analysis methods in a metaphor way and expanded its application in different scales such as global, national, urban agglomeration and city to support the process of multi-scale regional sustainable development.

Co-authored by the discoverer of the piezotronic effect, this book is a fundamental and comprehensive survey of piezotronics and piezo-phototronics. Piezotronics is a term broadly applied to devices fabricated using the piezopotential as a “gate” voltage to tune/control charge carrier transport at a contact or junction. The piezo-phototronic effect describes the use of the piezopotential to control the carrier generation, transport, separation and/or recombination for improving the performance of optoelectronic devices. The book first introduces the theory of the piezotronic effect and...
