Nanoelectronic devices are being extensively developed in these years with a large variety of potential applications. In this article, some recent developments in nanoelectronic devices, including their principles, structures and potential applications are reviewed. As nanodevices work in nanometer dimensions, they consume much less power and function much faster than conventional microelectronic devices. Nanoelectronic devices can operate in different principles so that they can be further grouped into field emission devices, molecular devices, quantum devices, etc. Nanodevices can function as sensors, diodes, transistors, photovoltaic and light emitting devices, etc. Recent advances in both theoretical simulation and fabrication technologies expedite the development process from device design to prototype demonstration. Practical applications with a great market value from nanoelectronic devices are expected in near future.

“…Both Hg and Cu ions can be detected using appropriate functionalization and these sensors are also re-uable after washing (13,14) . Finally, Shellfish diseases (Perkinsus species infections cause widespread mortality in both natural and farmed oysters) and Vitellogenin, an endocrine disrupter biomarker, in fish, have been detected at low concentrations (15)(16)(17)(18) . Table 1 shows a summary of the sensors we have made using HEMTs as the platform.…”

Recent progress in development of GaN-based transistors for gas and bio-sensing applications and amorphous IGZO layers for use thin film transistors (TFTs) on flexible substrates, including paper, is presented. For the detection of gases such as hydrogen, the gateless GaN transistors are typically coated with a catalyst metal such as Pd to increase the detection sensitivity at room temperature. Functionalizing the surface with oxides, polymers and nitrides enhances the detection sensitivity for gases and ionic solutions. The use of enzymes or antibody layers on the surface leads to highly specific detection of a range of antigens of interest in the medical and security fields. We give examples showing sensitive detection of glucose, prostate cancer and breast cancer markers and the integration of the sensors with wireless data transmission systems. The amorphous transparent conducting oxide InZnGaO 4 (IGZO) is attracting attention because of its high electron mobility, high transparency in the visible region and its ability to be deposited with a wide range of conductivities. This raises the possibility of making low-cost electronics on a range of arbitrary surfaces, including paper and plastics. Remaining obstacles to use of IGZO TFTs are presented. Applications of GaN Based Electronics and PhotonicsOn the photonics side, the AlGaInN materials system, consisting of the AlGaN/GaN, InAlN/GaN and InGaN/GaN heterostructures and the GaN,AlN and InN binaries is widely used in blue/violet/white/UV light emitting diodes for stoplights and full color displays, blue and green lasers for use in high density CD-ROM storage and high resolution printers. The main applications for GaN-based high power microwave transistors is in phased array radar systems and wireless communication systems, while the low noise, radiation hard transistors can be used in high temperature sensors and space-flight instrumentation (1)

“…Therefore, ZnO nanostructures have attracted great interest of researchers and engineers because of their excellent physical properties with enormous potential in technology. For example, nanowires [1][2][3][4][5][6][7][8][9] were synthesized in laboratories for optoelectronic sensors and Zhou et al, observed by density functional theory, that ZnO nanowires act as excellent chemical sensors 7,8,[10][11][12] . In special, theoretical studies [13][14][15] showed that thin films of ZnO combined with carbon nanotubes have interesting physical properties, such as weightlessness, elasticity and piezoelectricity.…”
