ATENEO DI QUALITÀ ACCREDITATO ANVUR - FASCIA A

3 Dicembre 2014 - Ore 16:30 - Seminario di Dipartimento - Enrico Prati - Atomic scale nanoelectronics: advancements and directions

Luogo: Aula Newton

Relatore: Enrico Prati - Consiglio Nazionale delle Ricerche -  Istituto di Fotonica e Nanotecnologie - Milano

Abstratc:

I review the theoretical and experimental advances in

nanometric-scale   devices and single atom systems. Few electron devices

are currently   obtained either by fabricating nanometric-scale

semiconductor FinFETs   and quantum dots, or by doping them with few

impurity atoms. Such nanometric devices, originally realized by employing

either pre-industrial or laboratory processes, are now being fabricated in

  commercial 14 nm node architecture. They have lead, starting from the

90's, to the observation of classical non-linear effects, to spin- and

orbital-related quantum effects, manipulation of  few qubits  and to

many-body quantum effects. I highlight high points and major

constraints and limitations to state-of-the-art fabrication based on

lithography and doping, and their possible integration with different

methods such as self-assembly, inspired by biology and natural systems.

"At the atomic level, we have new kinds of forces and new kinds of

possibilities, new kinds of effects. The problems of manufacture and

reproduction of materials will be quite different. I am, as I said,

inspired by the biological phenomena in which chemical forces are used

in repetitious fashion to produce all kinds of weird effects (one of

which is the author). R. Feynman, 1957"
