Book Description
The fundamental principle of piezotronics and piezo-phototronics were introduced by Wang in 2007 and 2010, respectively. Due to the polarization of ions in a crystal that has non-central symmetry in materials, such as the wurtzite structured ZnO, GaN and InN, a piezoelectric potential (piezopotential) is created in the crystal by applying a stress. Owing to the simultaneous possession of piezoelectricity and semiconductor properties, the piezopotential created in the crystal has a strong effect on the carrier transport at the interface/junction. Piezotronics is for devices fabricated using the piezopotential as a “gate” voltage to control charge carrier transport at a contact or junction. The piezo-phototronic effect uses the piezopotential to control the carrier generation, transport, separation and/or recombination for improving the performance of optoelectronic devices, such as photon detector, solar cell and LED. The functionality offered by piezotroics and piezo-phototronics are complimentary to CMOS technology. There is an effective integration of piezotronic and piezo-phototronic devices with silicon based CMOS technology. Unique applications can be found in areas such as human-computer interfacing, sensing and actuating in nanorobotics, smart and personalized electronic signatures, smart MEMS/NEMS, nanorobotics and energy sciences. This book introduces the fundamentals of piezotronics and piezo-phototronics and advanced applications. It gives guidance to researchers, engineers and graduate students.

Book Description
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 its applications in transistors, sensors, and catalysis. Subsequent chapters comprehensively cover the fundamentals of the piezo-phototronic effect and its impacts on photon sensors, solar cells, and LEDs. The updated and significantly expanded second edition covers the most recent advances and breakthroughs in this field over the last decade — gas, chemical, and biological nanosensors; quantum dots, wells, and wires; piezocatalysis; the piezo-photonic effect; and the pyro-phototronic effect. This seminal book serves as a basic text for scientists and students in the field of piezotronic devices and third-generation semiconductors.
