Sensitivity of Ion Absorption of Room Temperature Operating Single Electron Transistors

Nanoelectronic devices form the building blocks of the nanoscaled systems and require innovative technologies for their realization. Single Electron Transistors (SET) is a novel class of nano transistor which operates on the principle of Coulomb blockade. Coulomb blockade effects become dominant when the device dimensions approach few nano-meters. The SET devices are potential candidates for ap...

Surface Acoustic Wave (SAW) for Chemical Sensing Applications of Recognition Layers †

Surface acoustic wave (SAW) resonators represent some of the most prominent acoustic devices for chemical sensing applications. As their frequency ranges from several hundred MHz to GHz, therefore they can record remarkably diminutive frequency shifts resulting from exceptionally small mass loadings. Their miniaturized design, high thermal stability and possibility of wireless integration make ...

Simultaneous Surface Manipulation and Sensing in a Biosensor Using a Hexagonal Saw Device

We present the development of a hexagonal surface acoustic wave (SAW) device to simultaneously sense and manipulate the biological sensing film in biosensor applications. The primary objective is to improve sensitivity and selectivity. A secondary objective is to regenerate the sensor for reuse. A hexagonal device fabricated in 36° lithium tantalate allows for propagation of both Rayleigh and s...

TiO2 based surface acoustic wave gas sensor with modified electrode dimensions for enhanced H2 sensing application

The design and optimization of nanostructure-based surface acoustic wave (SAW) gas sensor is analyzed based on TiO2 sensing layer and modified electrode dimensions. The sensitivity of the gas sensor depends upon the type of sensing layer used and active surface area obtained by varying the aspect ratio. The performance of the sensor is observed from 0.1ppm to 100ppm concentration of ...
