Combination of electric fields and Joule self-heating is used to change the oxygen stoichiometry and promote oxygen vacancy drift in a freestanding (La,Sr)MnO 3 thin film microbridge placed in controlled atmosphere. By controlling the local oxygen vacancies concentration, we can reversibly switch our (La,Sr)MnO 3 -based microbridges from...

We investigate the resistive switching behaviour of VO2 microbridges under current bias as a function of temperature and thermal coupling with the heat bath. Upon increasing the electrical current bias, the formation of the metallic phase can progress smoothly or through sharp jumps. The magnitude and threshold current values of these sharp...

We used ink-jet printing technique to fabricate conducting silver circuits on two substrates of technological interest (alumina and insulating ceramic-glass) using a very simple and cost-effective reduction reaction of silver nitrate (AgNO3) aqueous solution followed by annealing in argon-5% hydrogen atmosphere. Commercial dishwashing detergent...
