DESCRIPTION:The design and realization of 1D systems incorporating well-de
 fined quantum heterostructures is regarded as a very promising route towar
 ds novel nanoelectronic and spintronic functionalities as well as photonic
 s integration. In this context\, the semiconductor nanowire technology pro
 vides a robust platform for the development of nano-heterostructures with 
 engineered electronic and optical properties.\nIn the Nanowire Group at th
 e NEST Laboratory of Scuola Normale Superiore (Pisa\, Italy) the unique pr
 operties of III-V semiconductor nanowires are exploited to develop innovat
 ive functional nanodevices. Our research interest is mainly focused on sin
 gle electron devices [1] and nanoscale thermoelectrics [2]. Besides\, we h
 ave recently proposed hybrid metal/semiconductor systems for electro-optic
 s applications\, and systems with doping-engineering for nano-plasmonics [
 3].\nI will illustrate how\, starting from InAs/InP nanowires implementing
  quantum dots (QDs)\, we achieved electrostatic control of the spin config
 uration in few electron systems using a method which exploits the Stark ef
 fect [1]. This allowed us to independently address the filling of two QDs 
 separated by only few nanometers\, leading to a fully-functional device wi
 thout the need of implementing any challenging nanoscale gating architectu
