Biodegradable junctionless transistors with extremely simple structure are fabricated at room temperature. The free-standing sodium alginate (SA) membrane is used as both a substrate and the dielectric layer for the transistors. The source/drain electrodes and the channel region are made of one single patterned Al:ZnO (AZO) thin film. The proposed transistors can be operated at a low voltage of 1...
Pulsed magnets were characterized as injection in the top-up mode for Taiwan Photon Source (TPS). Two in vacuum kicker magnets were exhibited to inject and extract electron beams for the booster ring. Besides, five septum and four kicker magnets of type in air were provided for injection into 3-GeV storage ring. All the pulsed magnets are of home design, manufacture and self-assembly at NSRRC. To...
Determination of morphology and size distribution of primary and secondary abrasives of slurry is essential for optimization of CMP performance. The undiluted slurry was characterized in liquid phase using silicon based Nano-pipettes in TEM. To validate utility of Nano-pipettes, comparatively quantitative analysis was performed by cryo-TEM technique.
Pulsed magnets including septum magnets and kicker magnets of type in vacuum serve to inject and to extract the electron beams for the booster ring in Taiwan Photon Source (TPS), which is a third-generation synchrotron accelerator. The design of the magnetic fields of the kicker and septum was simulated with OPERA 2D and 3D models. To verify the quality of the magnetic field and the distribution of...
In this work, using chirped pulse excitation pump-probe technique, we present the results of a study of carrier dynamics modulation in low-temperature-grown GaAs. Increasing carrier relaxation times as varying the excitation chirped conditions from negative to positive is demonstrated and explained by spectral dependence of carrier dynamics in Shockley-Read Hall model. We also indicate that chirped...
We demonstrate the fabrication of ZnSe nanoparticles using fs laser pulses. Following the irradiation of fs laser pulses at a wavelength of 800 nm and pulse duration of 100 fs, many hexagonal-phase ZnSe nanoparticles formed on the surface of an undoped (100) cubic ZnSe single-crystal wafer. The interesting phase transition from the cubic structure of ZnSe single-crystal wafer to the hexagonal structure...
Fabrication of a temperature sensor array and a heater in a complicated heat transfer microchannel system, on a glass substrate, is presented. In addition to the glass substrate, low thermal conductivity materials such as SU-8, PMMA plate are selected to form the micro channel wall to provide good thermal insulation. Both the titanium and the platinum are deposited sequentially on a glass plate and...
