Abstract: The main objective of this project is the fabrication and development of some electronic devices, having all in common a technology based on nano-core- shell NCS nanocomposite type. In IEEE Spectrum (2014), some NASA researchers claimed that the vacuum transistors or transistors made by Nothing are the immediate future devices suitable for co-integration within CMOS ICs. We start this project from preliminary results, developed in a POSDRU PostDoc Project (closed in 2013), accompanied by 12 papers, 2 patent about Organic thin film transistors (OTFT) and so called Nothing On Insulator (NOI) transistor - as exponents of thin film on insulator devices. For the first time, is offered a real solution to manufacture the NOI transistor, particularly by NCS- multi-layers assembling, validated by experimental tests. The CNT-related materials are promising to create NOI devices as alternative nanomaterials. Despite to a rapid progress of technology, OTFT with reasonable electronic characteristics, in absence of toxic precursors, remains a serious challenge. To improve the OTFT device performances we envisage the structure optimization by Silvaco tools simulations. To fabricate OTFT we select green routes, electing nanocomposites coated by green organic conductive polymers doped with organic ions to offer p or n type semiconductor behavior. This proposal has an interdisciplinary character, create a bridge nanotechnology for simple-TFT, SOI/NOI transistors and OTFT, get an innovative character by NCS nanocomposites and green-polymers used in nanoelectronics, respond to the international demands about other devices than CMOS to be co-integrated and offer room temperature technology for transistors, avoiding ultra-expensive clean room conditions. The disseminations mainly envisage papers publishing in ISI journals with accent to red-yellow code, conferences participation, 1 patent, 1 book or chapter, 1 IEEE Workshop, 1 Colloquium, 2 socio-cultural meetings.
