Elsevier Semiconductor Nanodevices: Physics, Technology and Applications: Volume 20 (Frontiers of Nanoscience, Volume 20)

Semiconductor Nanodevices: Physics, Technology and Applications explores recent advances in the field. The behaviour of these devices is controlled by regions of nanoscale dimensions which typically determine the local density of electronic states and lead to the observation of a range of quantum effects with significant potential for exploitation. The book opens with an introduction describing the development of this research field over the past few decades which contrasts quantum-controlled devices to conventional nanoscale electronic devices where an emphasis has often been placed on minimising quantum effects. This introduction is followed by seven chapters describing electrical nanodevices and five chapters describing opto-electronic nanodevices; individual chapters review important recent advances. These chapters include specific fabrication details for the structures and devices described as well as a discussion of the physics made accessible. It is an important reference source for physicists, materials scientists and engineers who want to learn more about how semiconductor-based nanodevices are being developed for both science and potential industrial applications. The section on electrical devices includes chapters describing the study of electron correlation effects using transport in quantum point contacts and tunnelling between one-dimensional wires; the high-frequency pumping of single electrons; thermal effects in quantum dots; the use of silicon quantum dot devices for qubits and quantum computing; transport in topological insulator nanoribbons and a comprehensive discussion of noise in electrical nanodevices. The optical device section describes the use of self-assembled III-V semiconductor nanostructures embedded in devices for a range of applications, including quantum dots for single and entangled photon sources, quantum dots and nanowires in lasers and quantum dots in solar cells. Review A detailed examination of the fabrication techniques and application areas of semiconductor-based nanodevices From the Back Cover Semiconductor Nanodevices: Physics, Technology and Applications opens with a section describing the fundamental technical and scientific background to the recent research covered in the subsequent chapters. This provides a suitable background for graduate students. This section covers firstly sample fabrication and characterization techniques. The growth techniques, primarily Molecular Beam epitaxy and Metal Organic Chemical Vapour Deposition are used for the growth of high purity epitaxial materials. There is also an emphasis on self-assembled growth of quantum dots and nanowires. This is followed by a description of device fabrication techniques commonly used including optical and e-beam lithography, along with etching (wet and dry) used for the fabrication of mesas as well as ohmic contacts and gate contacts etc. Next comes a description of structural characterisation techniques. Finally, low-temperature electrical and optical measurement techniques is described. Individual chapters review important recent advances in a range of different areas relating to semiconductor nanodevices. These include specific fabrication details for the structures described as well as a discussion of the physics accessible using these structures and devices. It is an important reference source for materials scientists and engineers who want to learn more about how semiconductor-based nanodevices are being used in a range of industry sectors.
