Fundamental and Applied Aspects of Electronics Based on Single -Walled Carbon Nanotube Thin Films
… transistors could be used effectively as memory devices to values that are nearly negligible. Not only p-channel but also and n-channel and ambipolar devices have been achieved by use of simple polymer coating strategies. Complex digital circuits composed of nearly 100 SWNT TFTs have also been …

Characterization of Schottky barrier carbon nanotube transistors and their applications to digital circuit design
… a few caveats. Under standard conditions, the devices do not enter saturation. Also. it is shown that CNTFETs are ambipolar devices, with a minimum current at V[sub]ds/2. Despite this distinction from MOSFETs, CNTFETs show impressive voltage transfer characteristics (VTC), even at low voltages. …

2D Electron Systems in Undoped GaAs and InGaAs and Progress Towards Undoped GaAs Nano-Structures
… by further confining the carrier gas. Undoped devices, which use an externally applied electric field to form a potential well for carriers, replicating the effect of dopants in a doped device, can have higher carrier mobilities and a lower charge impurity background than doped devices. This …

Synthesis, Characterisation and Device Application of Silicon Nanoparticles produced by Mechanical Attrition
… threshold. The transistors function as ambipolar devices, where the dominance of either carrier is deteri mined by the sign and swing direction of the gate potential. The best transistors fabricated have a hole mobility of 2:63 10ô5cm2=V s and electron mobility 7:81 10ô7cm2=V s.

Electrical detection of atmospheric pollutants and detergents on silicon
… nitrogen dioxide (NO2), and silicon surfaces on ambipolar silicon junctionless nanowire transistors (Si-JNTs) (Chapter 2). Experimental work and density functional theory (DFT) modelling demonstrate that NO2 functions as a "pseudo" molecular dopant, influencing key device parameters across p-type …
