Pentacene stands out as a model molecule among organic semiconductors due to its ability form well-ordered films that show high field effect mobility. We discuss the processes involved in pentacene film growth, emphasizing differences with respect inorganic films. The influence of growth parameters such substrate nature and temperature, deposition rate, kinetic energy molecular beam on structure morphology are discussed. Finally, we overview recent attempts nucleation draw attention role...
Organic electrochemical transistors (OECTs) are attracting a great deal of interest for biosensing and bioelectronics applications. However, their device physics is not yet well-understood. In this paper, we focus on the effect gate electrode material response OECTs. We studied OECTs made from conducting polymer poly(3,4-ethylenedioxythiophene) doped with poly(styrene sulfonate), which utilized halide electrolytes. demonstrate that Ag electrodes show larger current modulation compared to Pt...
This perspective deals with the coupling of ionic and electronic transport in organic devices, focusing on electrolyte-gated transistors. These include field-effect transistors (EG-OFETs) electrochemical (OECTs). EG-OFETs, based molecules polymers, can be operated at low electrical bias (about 1 V or below) permit unprecedented charge carrier densities within transistor channel. OECTs aqueous environment as efficient ion-to-electron converters, thus providing an interface between worlds...
Selective detection of bioanalytes in physiological fluids, such as blood, sweat or saliva, by means low-cost and non-invasive devices, is crucial importance to improve diagnosis prevention healthcare. To be really useful everyday life a sensing system needs handy, non-invasive, easy read possibly wearable.

Memristors are widely considered as promising elements for the efficient implementation of synaptic weights in artificial neural networks (ANNs) since they resistors that keep memory their previous conductive state. Whereas demonstrations simple (e.g., a single-layer perceptron) based on memristors already exist, more complicated is challenging and has yet to be reported. In this study, we demonstrate linearly nonseparable combinational logic classification (XOR task) using network...
Drought stress imposes a major constraint over crop yield and can be expected to grow in importance if the climate change predicted comes about. Improved methods are needed facilitate management via prompt detection of onset stress.

The device was integrated within plant’s stem, thereby allowing for continuous monitoring physiological status throughout its...
We use a seeded supersonic molecular beam to control the kinetic energy of pentacene (${\mathrm{C}}_{22}{\mathrm{H}}_{14}$) during deposition and growth on Ag(111). Highly ordered thin films are grown at low substrate temperatures ($\ensuremath{\sim}200\text{ }\mathrm{K}$) energies few electron volts, as shown by He diffraction x-ray reflectivity spectra. In contrast, thermal molecules yields only amorphous films. Growth room or higher temperature substrates poorer quality irrespective...
