NARROW CHANNEL Si-MOSFETs FOR ELECTRON TRANSPORT STUDIES

We have fabricated narrow channel Si-MOSFETs for electron transport studies at low temperature. The fabrication process combines optical lithography for large structures and high resolution e-beam lithography for narrow gates. The smallest working devices have a 0.14 pm wide gate. This paper reports the fabrication process and gives some examples of the quantum transport phenomena observed in t...

Highly conductive Sb-doped layers in strained Si

The ability to create stable, highly conductive ultrashallow doped regions is a key requirement for future silicon-based devices. It is shown that biaxial tensile strain reduces the sheet resistance of highly doped n-type layers created by Sb or As implantation. The improvement is stronger with Sb, leading to a reversal in the relative doping efficiency of these n-type impurities. For Sb, the p...

Magneto-optics of electronic transport in nanowires

Effects of irradiation on the electronic conductance in nanowires, for field-free conditions and under the influence of applied longitudinal magnetic fields, were investigated. The nanowires were modeled within the free-electron framework with a parabolic ~transverse! confining potential. Our results for the dependence of the photoconductance of irradiated nanowires on the photon energy and/or ...
