  2. 1. Tunnel Emitter Transistors

    Author : Erik Aderstedt; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TET; tunneling; siO2< sub>; tunnel emitter transistor; MOS; Ta2< sub>O5< sub>; silicon; high- #954; BICFET; dielectrics;

    Abstract : The Tunnel Emitter Transistor is based on the modulation of the tunnel current in a Metal Oxide Semiconductor (MOS) structure with an ultra-thin oxide layer. The modulation is accomplished by injecting charge to the oxide-semiconductor interface from a third terminal. READ MORE

  4. 2. Risk Management in Tunneling Projects : Estimation and Planning

    Author : Mohammad Mohammadi; Johan Spross; Fredrik Johansson; Stefan Larsson; Anna Kadefors; Amund Bruland; KTH; []
    Keywords : Cost overrun; Transport infrastructure projects; Time and cost estimation; Probabilistic approaches; Tunneling; Soil and Rock Mechanics; Jord- och bergmekanik;

    Abstract : Cost overruns and schedule delays are frequently observed occurrences in the construction of transport infrastructure projects. Such phenomena lead to the mismanagement of significant amounts of both public and private resources. READ MORE
