--------------2DA7E699163B21EF6E9F7AAB Content-Type: text/plain; charset=us-ascii Content-Transfer-Encoding: 7bit I am a Spaniard working in the field of Transparent Conductive Thin Films (in particular, Al doped ZnO thin films) for a year. My project requires me to prepare by assisted CVD methods (mainly plasma assisted and ion beam assisted) and characterize these thin films. Can anyone kindly suggest some books or literature available on electrical characterization of conductive thin films (thickness lower than 500 nm) by Hall measurements by the van der Pauw method?. In particular, I need to know as many relevant experimental details as possible (sample dimensions, how to make the electrode contacts, values of the current and/or magnetic field applied, technical description of the instruments used (power supply unit, voltimeter, amperimeter, Hall sensor, electromagnet, electrical noise filters, ...) in order to "make" my own experimental set up. In these kind of "conductors", the lower resistivity, according with literatue, is around 5.10-4 Ohms.cm, the higher carrier concentration between 10-19 10-20 cm-3 and their mobility is around 25 cm-2/Vs. Any suggestions will be wellcome.
