1. 1. Electrical Characterization of Silicon Nanogaps

   Författare :Jonas Berg; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Organic molecules; Molecular electronics; Surface leakage currents; Low-frequency noise; Soft breakdown; TSRAM; Resonant tunneling diodes; Selective etching; Silicon nanogaps; Nanocontacts;

   Sammanfattning : We have designed and manufactured silicon nanogaps aimed at electrically interfacing molecules, utilizing the precision thickness control in an oxidation process. An insulating layer was formed on a silicon wafer, and then polysilicon was deposited on top. LÄS MER

   Sammanfattning : Transistor models are very important in the design of Monolithic Microwave Integrated Circuits (MMICs). Circuit simulations based on accurate transistor models are one of the keys to high circuit yield. Transistor models can also be used to trace problems in the device fabrication processes. LÄS MER
