Realization of Silicon Nano-structured layers on Glass substrates suitable for light emitting diodes

Darbari S., Shahmohammadi M., Mohajerzadeh S., Robertson M.D., Thin Film and Nanoelectronics Laboratories, IR

Si-nano-crystal (Si-nc) layers with luminescent behavior on glass substrate have been prepared using a time multiplexed plasma hydrogenation and reactive ion etching at temperatures below 450oC. Various techniques such as SEM, Photo-luminescent and TEM analyses [...]

Controllable Sequential Low Temperature Plasma Assisted Growth of Vertical Multi-wall & Single-wall CNTs

Kolahdouz Z., Darbari S., Mohajerzadeh S., University of Tehran, IR

By investigating the effects of growth parameters of CNTs, we have arrived at small diameter, single/multi-wall nanotubes at low temperatures. Synthesis of CNTs was performed using the gas mixture of the C2H2/CH4 gas and H2 [...]

Novel interdigital actuators and sensors based on highly overlapped branched carbon nanotubes

Darbari S., Abdi Y., Ebrahimi A., Mohajerzadeh S., University of Tehran, IR

This work presents a novel interdigital structures of branched carbon nanotubes on silicon-based membranes where the heavy overlapping between neighboring lines leads to a high capacitance. The value of the capacitance is so high (of [...]
