  2. 1. Graphene Hot-electron Transistors

    Author : Sam Vaziri; Mikael Östling; Max Lemme; Suman Datta; KTH; []
    Keywords : Graphene; hot-electron transistors; graphene base transistors; GBT; cross-plane carrier transport; tunneling; ballistic transport; heterojunction transistors; graphene integration; graphene transfer; Informations- och kommunikationsteknik; Information and Communication Technology;

    Abstract : Graphene base transistors (GBTs) have been, recently, proposed to overcome the intrinsic limitations of the graphene field effect transistors (GFETs) and exploit the graphene unique properties in high frequency (HF) applications. These devices utilize single layer graphene as the base material in the vertical hot-electron transistors. READ MORE

  4. 2. 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

  5. 3. Organic Electrochemical Transistors : Materials and Challenges

    Author : Silan Zhang; Simone Fabiano; Magnus Berggren; Jenny Nelson; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : The use of organic mixed ionic-electronic conductors (OMIECs) has demonstrated the potential to transform the field of bioelectronics, spanning from medical diagnostics to neuromorphic computing hardware. To keep up with the fast-paced demands, it is crucial to develop customizable device fabrication, design new materials, improve operation stability, and explore the ion-electron interactions within OMIECs.
