Innovative nanowire-based prototypical device architectures with potential applications encompassing quantum technologies [1] and nanoelectronics [2,3] have been recently enabled by iontronics [4], combining semiconductor nanowires with (poly)electrolytes where ions are free to move upon electrical or thermal biases. These devices are multi-gate nanotransistors which exploit electrolytes as dielectrics to build up electric double layers at the nanowire-electrolyte interface, providing ultra-intense local electric fields that can be tailored to control the transport properties in the nanowire. Implementing this paradigm, ion-gated and ion-sensitive nanowire transistors were proven to enable alternative measures of electrical parameters as well as novel architectures for thermoelectrics, and more recently have been proposed for zero-dimensional density of states engineering in InAs nanowires, namely, for engineering the iontronic nanowire quantum dot. Notably, such quantum features observed at low temperature have been very recently identified as potential booster of neuromorphic fiunctionalities. brief review of nanowire iontronics is discussed and the novel concept of quantum iontronics in nanowire-based devices is reported.

nanoGe is a prestigious brand of successful science conferences that are developed along the year in different areas of the world since 2009. Our worldwide conferences cover cutting-edge materials topics like perovskite solar cells, photovoltaics, optoelectronics, solar fuel conversion, surface science, catalysis and two-dimensional materials, among many others.
Previously nanoGe Spring Meeting (NSM) and nanoGe Fall Meeting (NFM), MATSUS is a multiple symposia conference focused on a broad set of topics of advanced materials preparation, their fundamental properties, and their applications, in fields such as renewable energy, photovoltaics, lighting, semiconductor quantum dots, 2-D materials synthesis, charge carriers dynamics, microscopy and spectroscopy semiconductors fundamentals, etc.
International Conference on Hybrid and Organic Photovoltaics
International Conference on Hybrid and Organic Photovoltaics (HOPV) is celebrated yearly in May. The main topics are the development, function and modeling of materials and devices for hybrid and organic solar cells. The field is now dominated by perovskite solar cells but also other hybrid technologies, as organic solar cells, quantum dot solar cells, and dye-sensitized solar cells and their integration into devices for photoelectrochemical solar fuel production.
Asia-Pacific International Conference on Perovskite, Organic Photovoltaics and Optoelectronics
The main topics of the Asia-Pacific International Conference on Perovskite, Organic Photovoltaics and Optoelectronics (IPEROP) are discussed every year in Asia-Pacific for gathering the recent advances in the fields of material preparation, modeling and fabrication of perovskite and hybrid and organic materials. Photovoltaic devices are analyzed from fundamental physics and materials properties to a broad set of applications. The conference also covers the developments of perovskite optoelectronics, including light-emitting diodes, lasers, optical devices, nanophotonics, nonlinear optical properties, colloidal nanostructures, photophysics and light-matter coupling.
The International Conference on Perovskite Thin Film Photovoltaics Perovskite Photonics and Optoelectronics (NIPHO) is the best place to hear the latest developments in perovskite solar cells as well as on recent advances in the fields of perovskite light-emitting diodes, lasers, optical devices, nanophotonics, nonlinear optical properties, colloidal nanostructures, photophysics and light-matter coupling.
