2. 1. Photochromism - Logic and Biologic Approaches

   Author : Martin Hammarson; Chalmers tekniska högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; DNA-binding; molecular logic; dithienylethene; photochromism; DNA; photoswitch; spiropyran;

   Abstract : Photochromism is the light-induced colour change of molecules called photo-chromic compounds. The isomerisation causes changes in the electronic properties of the molecules and rearrangements of bonds which can be used in many more applications than the observed colour change. READ MORE

4. 2. All Around Logic Synthesis

   Author : Maxim Teslenko; Hannu Tenhunen; Michel Berklaar; KTH; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; graph dominators; FPGA mapping; redundancy removal; RBN; Computer science; Datavetenskap;

   Abstract : This dissertation is in the area of Computer-Aided Design (CAD) of digital Integrated Circuits (ICs). Today's digital ICs, such as microprocessors, memories, digital signal processors (DSPs), etc., range from a few thousands to billions of logic gates, flip-flops, and other components, packed in a few millimeters of area.

5. 3. Quantum and Ballistic Nanodevices

   Author : Ivan Shorubalko; Fasta tillståndets fysik; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; III-V semiconductors; low-dimensional structures; nanostructures; ballistic rectifiers; three-terminal ballistic junctions; quantum wires; planar quantum dots; logic gates; harmonic generation; InP; GaInAs; nanoelectronics; Fysik; Physics; nonlinear transport; electron transport; quantum nanodevices; ballistic nanodevices; Fysicumarkivet A:2003:Shorubalko;

   Abstract : In this thesis, electron transport in quantum and ballistic devices was studied. The devices studied here were quantum wires, planar quantum dots, ballistic rectifiers, artificial functional materials, and three-terminal ballistic junctions. The possible application of such devices in the future nanoelectronics was also investigated. READ MORE

6. 4. Process Design Kit and High-Temperature Digital ASICs in Silicon Carbide

   Author : Muhammad Shakir; Carl-Mikael Zetterling; B. Gunnar Malm; Philip Mawby; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Silicon Carbide; high-temperature digital integrated circuits; process design kit PDK ; bipolar logic gates; transistor-transistor logic TTL ; TTL CPU; bipolar transistor; LSI Circuits; ASICs; Informations- och kommunikationsteknik; Information and Communication Technology;

   Abstract : Electronics such as microprocessors are highly demanded to monitor or control a process or operation in temperature critical (300 ºC to 600 °C) applications. State-of-the-art silicon-based integrated circuits (ICs) have been improved significantly throughout the years but mainly for a low-temperature ambient. READ MORE

7. 5. Controlling the Fluorescence Properties of Diarylethene-based Photochromic Systems

   Author : Gaowa Naren; Chalmers tekniska högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; isomerization; color change; photochromic molecules; molecular logic; intensity modulation; diarylethene; RGB; all-photonic; FRET;

   Abstract : Diarylethene (DAE) photoswitches are one of the most promising families of photochromic molecules because of their outstanding photophysical/photochemical properties. This class of compounds, which can photoisomerize between an open colorless and a closed colored form, has been applied in various fields in this thesis work, spanning one-color fluorescence intensity modulation, all-photonic full-color reproduction, light-induced color changes for molecular logic gates and information processing.
