The design criteria for large transconductance/high output impedance or high-gain operation of metal-oxide tunneling transistors is given. The dependence of the gate control on the aspect ratio of thickness to width of the tunneling oxide is investig

We describe a simple and reliable process for the fabrication of nanometer-scale structures by using the local electric field of a conducting tip atomic force microscope to write surface oxide patterns by local anodic oxidation. These oxide patterns

Two approaches were developed using an ambient atomic force microscope (AFM) to pattern metal in either positive or negative tone. The difference in surface chemical reactivity between exposed and unexposed regions was used to selectively attach coll

AFM-generated surface modifications are used to fabricate free-standing Si nanostructures. We employ the local electric field of a metal-coated AFM tip which is operated in air to selectively oxidize regions of a H-passivated Si surface. The resultin

We describe a simple and reliable process for the fabrication of nanometre-scale silicon structures by using the local electric field of a proximal probe tip (either an STM or a conducting tip atomic force microscope) to write surface oxide patterns

The advantage of a low voltage approach to lithography and surface modification is that a more spatially localized energy deposition can be achieved than with a focused high energy charged particle beam. Proximal probes, such as the scanning tunnelli

We report the scaling behavior of 1∕f noise in single-walled carbon nanotube devices. In this study we use two-dimensional carbon nanotube networks to explore the geometric scaling of 1∕f noise and find that for devices of a given resistance the

We report the use of carbon nanotubes as a sensor for chemical nerve agents. Thin-film transistors constructed from random networks of single-walled carbon nanotubes were used to detect dimethyl methylphosphonate (DMMP), a simulant for the nerve agen

We report on the transport properties of random networks of single-wall carbon nanotubes fabricated into thin-film transistors. At low nanotube densities (∼1 μm−2) the networks are electrically continuous and behave like a p-type semiconductor w

We report the fabrication of nanometer-scale conducting silicon wires by the STM-induced modification of a passivated silicon (100) surface followed by a selective liquid etch. The modified surface layer is a thin oxide a few monolayers thick which a
