The combination of scanning tunneling microscopy (STM) with time-of-flight mass system (TOF-MS) adds new information to STM imaging. In this study, an STM system has been combined with laser excitation and was used for desorption and ionization of surface molecules, without the use of any other external stimulus. Desorbed ions from confined areas were accelerated and detected by a TOF chamber. We...
Semiconductive polythiophene derivate polymers show electroluminescence (EL) properties if excited under opportune conditions and can be used as active element in novel efficient light-emitting diodes (LEDs) or in photovoltaic applications as detectors or solar cells. These intriguing and innovative materials are so far studied in bulk condition, under the excitation of two macroscopic electrodes,...
