WIDE BANDGAP NANOWIRES

Comprehensive resource covering the synthesis, properties, and applications of wide bandgap nanowires

This book presents first-hand knowledge on wide bandgap nanowires for sensor and energy applications. Taking a multidisciplinary approach, it brings together the materials science, physics and engineering aspects of wide bandgap nanowires, an area in which research has been accelerating dramatically in the past decade. Written by four well-qualified authors who have significant experience in the field, sample topics covered within the work include:
_ Nanotechnology-enabled fabrication of wide bandgap nanowires, covering bottom-up, top-down and hybrid approaches
_ Electrical, mechanical, optical, and thermal properties of wide bandgap nanowires, which are the basis for realizing sensor and energy device applications
_ Measurement of electrical conductivity and fundamental electrical properties of nanowires
_ Applications of nanowires, such as in flame sensors, biological sensors, and environmental monitoring

For materials scientists, electrical engineers and professionals involved in the semiconductor industry, this book serves as a completely comprehensive resource to understand the topic of wide bandgap nanowires and how they can be successfully used in practical applications.
