We demonstrate a self-rectifying, compliance-free, BEOL CMOS-compatible, resistive switching memory device, with nonfilamentary switching mechanism, forming-free operation, analog switching behavior and excellent device to device operation uniformity, down to the smallest device size. The cells have a reset switching current density of ∼0.3MA/cm2 (and ∼10x lower set current). This corresponds to ∼5uA...
An energy recovery system using a four-stage depressed collector was simulated and designed to improve the overall efficiency of the W-band gyrotron backward wave oscillator (gyro-BWO) in the University of Strathclyde. The spent beam information was exported from the simulation of the gyro-BWO using the 3D PIC code MAGIC. The geometry of the depressed collector was optimized using a genetic algorithm...
In this work, we present the fabrication method and the experimental results of a dielectrophoretic (DEP) device for particle batch separation. The curved parts of serpentine microchannel that causes performance deterioration in capillary electrophoresis (CE) due to the plug dispersion are effectively used in our design for dielectrophoretic separation. The top-and-bottom focusing electrodes are employed...
In this paper, the problem of strain was discussed, which comes from the process of eliminating the bow by cooling. During this process, the deformation was analyzed by measuring strains at different places of a solar cell. At last, some phenomena were got by comparing strain caused by cooling and heating respectively.
In this work, a novel device for batch separation of particles based on dielectrophoresis (DEP) is presented. The curved parts of serpentine micro-channel that causes performance deterioration in capillary electrophoresis (CE) due to the plug dispersion are effectively used in our design for dielectrophoretic separation. The top-and-bottom focusing electrodes are employed in the intermediate straight...
Current paper describes the fabrication and testing of a Lab-on-a-chip device using TMMF S2030 dry film resist for single cell analysis. The device typically consists of a bigger channel (20 mum deep), 3 smaller channels (2 mum deep) with embedded reservoir in between and a detector towards the downstream.Whole device has been fabricated on a standard glass wafer. Electrode configuration is the notable...
In this work, we present a method to compensate the plug dispersion for the moving field capillary electrophoresis (CE) application. A forward electroosmotic pump (EOP) will be employed to compensate the back flow in the active separation segment. The required driving voltage of the EOP was analyzed as a function of the channel topology. Two channel topologies are proposed and investigated with the...
Current paper describes the testing, alignment and bonding of a PDMS-glass bonded microfluidic device used for single cell analysis. The channels were successfully tested using carboxylate modified polystyrene beads for any leakage. Polystyrene beads of 2 mum have been successfully trapped within the reservoir of the device by well known dielectrophoresis technique and the same technique will be used...
To realize the full potential of a Gyrotron backward wave oscillator (Gyro-BWO), an energy recovery system was designed using Particle-In-Cell (PIC) simulations and optimized using both a Genetic Algorithm and PIC simulations. Simulations were carried out to optimize a periodic structure for separation of the spent electron beam and the output radiation produced by a gyro-BWO in the 8.0 – 9.5GHz frequency...
We present a novel device for continuous separation based on dielectrophoresis (DEP), where the non-uniform electric field is generated by applying a dc voltage over a circular channel structure instead of ac electrodes. The finite element simulation result shows it has the potential to separate particles of different sizes and dielectric properties in both spatial and time domain. Compared with the...
