1. 1. Electron transport in quantum point contacts : A theoretical study

   University essay from Institutionen för datavetenskap, fysik och matematik, DFM

   Author : Alexander Gustafsson; [2011]
   Keywords : quantum point contact; mesoscopic physics; 2DEG; quantized conductance; Aharonov-Bohm; magnetoconductance; recursive Green s function; quantum Hall effect;

   Abstract : Electron transport in mesoscopic systems, such as quantum point contacts and Aharonov-Bohm rings are investigated numerically in a tight-binding language with a recursive Green's function algorithm. The simulation reveals among other things the quantized nature of the conductance in point contacts, the Hall conductance, the decreasing sensitivity to scattering impurities in a magnetic field, and the periodic magnetoconductance in an Aharonov-Bohm ring.

3. 2. Design and construction of ultrahigh vacuum system to fabricateSpintronic devices, fabrication and characterization of OMAR (organic magnetoresistance) devices

   University essay from Institutionen för fysik, kemi och biologi

   Author : Srikrishna Chanakya Bodepudi; [2009]
   Keywords : Organic spintronics; Organic based magnets; Magentoresistance; Organic magnetoresistance OMAR ;

   Abstract : This thesis concerns design and construction of an ultra high vacuum chamber to fabricate and characterize spintronic devices.  The long term intention is to fabricate spin valve structures with V[TCNE]2 (hybrid organic inorganic semiconductor room temperature magnet) sandwiched between two ferromagnetic electrodes, which requires better than 10-8mbar of vacuum.
