16 Jan 2013 | | Abstract: | The field-effect technique, popular thanks to its application in common
field-effect transistors, is here applied to metallic thin films by using as a
dielectric a novel polymer electrolyte solution. The maximum injected surface
charge, determined by a suitable modification of a classic method of
electrochemistry called double-step chronocoulometry, reached some units in
10^15 charges/cm^2. At room temperature, relative variations of resistance up
to 8%, 1.9% and 1.6% were observed in the case of gold, silver and copper,
respectively and, if the films are thick enough (> 25 nm), results can be
nicely explained within a free-electron model with parallel resistive channels.
The huge charge injections achieved make this particular field-effect technique
very promising for a vast variety of materials such as unconventional
superconductors, graphene and 2D-like materials. | | Source: | arXiv, 1301.3769 | | Services: | Forum | Review | PDF | Favorites | |
