Direct Nanoscale Sensing of the Internal Electric Field in Operating Semiconductor Devices Using Single Electron Spins

ACS Nano, 2017
The electric field inside semiconductor devices is a key physical parameter that determines the properties of the devices. However, techniques based on scanning probe microscopy are limited to sensing at the surface only. Here, we demonstrate the direct sensing of the internal electric field in diamond power devices using single nitrogen-vacancy (NV ...

Electrical characterization of gas sensing devices based on porous TiO2

physica status solidi (a), 2003
Electrical properties of two kinds of sandwich structures (SnO 2 :F/por-TiO 2 /Ti and Si/por-TiO 2 /Pd) are investigated by the methods of I-V, C-V characteristics and DLTS in vapors of water and alcohol. It has been demonstrated that besides the change of the conductivity and of the capacitance of the por-TiO 2 layers one can also use for gas sensing

PDIF-CN₂modified porous silicon optical and electrical transducers for biochemical sensing electrical and optical sensing by porous silicon devices

2014 Fotonica AEIT Italian Conference on Photonics Technologies, 2014
In this preliminary work, we report about porous silicon (PSi) non-symmetric optical microcavities as transducers modified by organic molecular beam deposition (OMBD) of N,N'-1H,1H-perfluorobutyldicyanoperylene-carboxydi-imide (PDIF-CN 2 ), an electrically conductive organic material.

Electrical parameters and gas sensing behaviour of ClInPc thin film devices

The European Physical Journal Applied Physics, 2008
The electrical characteristics of thermally evaporated Chloroindium phthalocyanine thin films (ClInPc) are studied. A number of parameters are evaluated on the basis of the theory of space-charge-limited conduction. ClInPc thin films are extremely stable, in terms of both resistance to chemical attack and thermally, no hysteretic was observed after ...

Paper-based analytical device coupled with Bi-MOF: Electric field amplification and fluorescence sensing of glyphosate

Analytica Chimica Acta, 2023
Glyphosate, a potent herbicide wildly used in the world, involves potential hazards to human health by accumulating in the food chain. Due to its absence of chromophores and fluorophores, the rapid visual detection of glyphosate has always been difficult.
