Electrical Characterization of Nanopolyaniline/Porous Silicon Heterojunction at High Temperatures

Silicon Bulk Mobility at High Ambient Temperatures

One of the goals of the PARASITICS project was the evaluation of decisive physical models in the high temperature range (300 K – 700 K) by comparison between simulation and electrical measurements of suitable test structures. Various van der Pauw devices were examined to test the microscopic-based mobility model of Schenk [1]. In order to make the comparison complete, calculated Hall factors as...

Characterization of Transistor Matching in Silicon-Germanium Heterojunction Bipolar Transistors

ACKNOWLEDGEMENTS I am deeply indebted to Dr. John D. Cressler for his patience, guidance, and support throughout my master's program. My inspiration came from his passion for research and his confidence in my abilities. Working under his leadership in such an exciting field was both educationally and professionally enriching. I would also like to thank the other members of my thesis advisory co...

Electrical characterization of transparent p – i – n heterojunction diodes

Transparent p – i – n heterojunction diodes are fabricated using heavily doped, p-type CuYO2 and semi-insulating i-ZnO thin films deposited onto a glass substrate coated with n-type indium tin oxide. Rectification is observed, with a ratio of forward-to-reverse current as high as 60 in the range 24–4 V. The forward-bias current–voltage characteristics are dominated by the flow of space-charge-l...

Electrical characterization of metal-molecule-silicon junctions.

Direct assembly of molecules onto silicon surfaces is of particular interest for potential employment in hybrid organic-semiconductor devices. In the study we report here, aryl diazonium salts were used to assemble covalently bound molecular groups on a hydride-passivated, oxide-free n-type Si(111) surface. The reaction of 4-(trimethylsilylethynyl)benzenediazonium tetrafluoroborate generates a ...
