Low-temperature polycrystalline-silicon thin-film transistor (LTPS TFT) has emerged as one of the promising candidates for low-power low-cost applications on flexible substrates. In this paper, we propose a statistical simulation methodology to estimate parametric variations in scaled LTPS TFT due to the inherent properties [such as the number, location, and orientation of grain boundaries (GBs)]...
The authors have measured spin precession from devices with 350 micron-thick undoped silicon transport layers in an oblique magnetic field synthesized by a static magnetic field Bpar and a varied magnetic field Bperp. Experimental results of spin precession, measured by changing the fixed in-plane magnetic field magnitude at zero device misalignment are also presented. Repeating this study at a fixed...
Conventionally a line defect in the photonic crystal (PhC) is used to create a waveguide for light propagation through the PhC. A PhC based filter is designed by introducing micro-cavities within the line defect so as to form the resonant bandgap structure for PhC. Such a PhC waveguide (PhCWG) filter shows sharp resonant peak in output wavelength spectrum. We proposed a suspended silicon bridge structure...
In this work, we propose a novel low power, process tolerant, generic and reconfigurable test structure to reduce the test cost, improve diagnosability and verifiability of complex VLSI systems. The test structure contains a variety of configurable design-for-test units designed with low cost low temperature poly crystalline silicon thin film transistors (LTPS TFTs) that are fabricated on a separate...
A line defect in a silicon two-dimensional (2-D) photonic crystal (PhC) is created as a waveguide for light propagation via the PhC. By introducing micro-cavities within the line defect so as to form the resonant band gap structure for PhC, we demonstrate a PhC waveguide (PhCWG) filter with clear resonant peak in output wavelength spectrum. We conceptualized a novel nanomechanical beam structure embedded...
Recently, the demand for ultra low-power and low-cost digital design has grown significantly due to the fast growth of battery-operated portable applications. Many such applications need circuits to be fabricated on flexible substrate such as polymer, glass etc. Low Temperature Polycrystalline Silicon Thin Film Transistors (LTPS-TFTs) have been a promising candidate to realize digital circuits on...
