Lecturer 1.”Functionality and Applications of Nanodot Devices”
Speaker Dr. Yasuo Takahashi ,
Graduate School of Information Science and Technology, Hokkaido University
Abstract Single-electron devices fabricated from nano-dots have attracted attention as devices that can control single electrons. At the core of this is the Single Electron Transistor (SET) composed of nanodots and tunneling barriers, from which electrons enter from the outside and leave via electrodes. In itself it is not so difficult to fabricate nanodots, but it is difficult to achieve tunnel barriers with controlled resistances, so most studies focus on only making an SET. A more fundamental discussion on to what extent response can be sped up by loweringt the tunnel resistance, or to what extent single electrons can be controlled, which should be the next step, has hardly been discussed. Here, we introduce the not well-known characteristics of single-electron devices that are based on Si single electron devices, and evaluate their properties.
Lecturer 2.”Brownian Motion-based Computing”
Speaker Dr. Jia Lee ,
Chongqing University, School of Computer Science
Abstract Particles such as atoms and molecules are constantly moving randomly at nanoscales due to thermal fluctuations. Called Brownian motion, such irregular behavior is considered incompatible with traditional computing models, which require tightly controlled behavior. In particular, the traditional model has been developed with the emphasis on correcting malfunction caused by noise or on minimizing noise. In biological systems such as those using motor protein molecules, thermal fluctuations cause randomness, which plays an important role in the activation of diverse and dynamic behavior of molecules. Based on similar processes of Brownian motion, computation schemes have been developed in which signals are represented by atoms or molecules that move around randomly. In such schemes, which have been recently proposed, the emphasis is not so much on eliminating randomness of signals to prevent a loss of control or information, but rather on using Brownian motion to explore the state space of computation, in a way resembling natural processes.
