1. 6. Design and Implementation of a 2-Channel High Precision and High Speed Digitizing system

   Master-uppsats, Lunds universitet/Institutionen för elektro- och informationsteknik

   Sammanfattning : Recently, new spectroscopic techniques have been developed such as photocurrent detected two-dimensional spectroscopy [1], which measure the response from a sample that is excited by a high intensity laser pulses. The responses are linear and nonlinear signals that have very different amplitudes; the linear signal can be from 103 to 105 times larger than the nonlinear signal. LÄS MER

3. 7. Structural and electrical characterization of graphene after ion irradiation

   Magister-uppsats, Experimentell fysik

   Författare :Di Cristo Valentina; [2010]
   Nyckelord :graphene;

   Sammanfattning : Graphene is a recently discovered material consisting of a two-dimensional sheet of Carbon atoms arranged in an hexagonal pattern. It is a zero-gap semimetal whose electrical properties can be tuned by controlled induction of defects such as vacancies. In this work, graphene flakes were produced with the standard method of mechanical exfoliation. LÄS MER
