In order to strengthen safety in abnormal environment, we analyze safety on the Solid State Thermal Mechanical Discriminator (SSTMD). Firstly, we calculate the number of Thermo-Mechanical Switches (TMSs) by means of a method with probability theory when the probability of unintentional unlock on the SSTMD is less than 10−6. Then the probability of safety failure on the SSTMD is estimated by analyzing...
NbO2-based selector with threshold switching characteristics was studied as a probable candidate to address the sneak-path problem in the resistive-switching random access memory(RRAM) arrays. In this work, we simulate the forming and switching process of the selector with consideration of the thermally driven metal-insulator transition and crystallization effects. Based on the simulator, we analyze...
The concept of atomically controlled processing for group IV semiconductors is based on atomic-order surface reaction control. This approach is especially important for the epitaxial deposition of very thin (nm) layers. Here, the existences of Ge oxide in the CVD reactor resulting from former Ge deposition and hydrogen termination of the wafer surface is impacting the epitaxial growth essentially...
A combined wafer bonding method consist of spot pressing bonding technique and water glass adhesive layer is proposed. The mechanism of water glass bonding is investigated, and the two major factors in this bonding method: surface energy and voids formation has also been discussed.
SnO2 nanoparticles synthesized by a simple precipitation method are doped with palladium and different concentrations of graphene to improve the ethanol sensing performance. By incorporating 0.1 wt% graphene and 3 wt% PdCl2 into SnO2, the sensor has good sensitivity and the working temperature could be down to 40 °C. The response time and recovery time of the gas sensor are also reduced to 1 s and...
In this letter, an atomistic-level simulation model of bipolar TiO2 RRAM is addressed, which adopts the typical MIM structure and combines the equation of oxygen vacancy transport, current continuity and Joule heating. Based on the model, the dynamic formation and rupture of conductive filament are described in a 3D geometry model of COMSOL. Besides, the electro-thermal model with a conical shape...
Oxide-based resistive random access memory (RRAM) has been widely studied as the promising candidate for the applications of next generations of data storage and computing technologies. In this paper, we will discuss the physical mechanism and optimization design of oxide-based RRAM devices, the novel RRAM-based computing/memory unifying architectures and the applications for data storage and computing...
In this paper, thermally aware optimized measurement of field programmable gate array (FPGA)-based systems using ring oscillator (RO)-based thermal sensors is proposed for thermal management. The sensor array was distributed uniformly on the FPGA in a novel layout, and was optimized on allocation using a trade-off between sensor number and measurement resolution. This method is suitable for various...
Graphene exhibits an extremely high in-plane thermal conductivity, which shows highly prospective value in thermal management and heat spreader application. In this work, graphene sheet was integrated into LED module as intermediate heat spreader with different schemes, and heat dissipation performance was measured and evaluated using standard InfraRed (IR) camera. The experimental data shows that...
