1. 1. Numerical modelling of hot electron transport in Schottky-diodes and heterojunction structures

   Författare :Hans Hjelmgren; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; n-GaAs; ; energy balance equations; dc-properties;

   Sammanfattning : A one-dimensional drift-diffusion model, including energy balance equations, is used to model Schottky-diodes and heterojunction structures. The set of equations are solved simultaneously with a finite-difference iterative scheme. LÄS MER

3. 2. d-wave Josephson Junctions

   Författare :Tobias Lindström; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Josephson junctions; high-temperature superconductivity; Andreev states;

   Sammanfattning : The properties of d-wave YBCO Josephson junctions and dc-SQUIDs with high misorientation angles have beenstudied experimentally .The predominant d-wave symmetry of the pairing wavefunction in high-Tc superconductors has, to a large extent, beena hinderance in applications, but it also makes it possible to fabricate devices with novel properties that may be suitablefor applications in the quantum regime; one particulary interesting property is a strong second harmonic component in the current-phase relation ofjunctions with the electrodes oriented in a node-lobe arrangement; so-called 0-45 junctions.

4. 3. Theoretical Investigation of Resonant-Tunneling Structures

   Författare :Anders Kindlihagen; K-F Brennan; Linköpings universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

   Sammanfattning : Resonant-tunneling structures are generally of great interest, both for technological applications and for basic theoretical research. This work focuses on the Double-Barrier Resonant-Tunneling Structure (DBRTS). We investigate both unipolar and bipolar DBRTSs. LÄS MER
