ULTRA-SOI is a new generation of the channel-potential-based non-charge-sheet model for the dynamic depletion (DD) Silicon-On-Insulator (SOI) MOSFET, developed by TSRC group in EECS department of Peking University with many year efforts. The model is formulated with a fully physical derivation from the Poisson's equation to solve the potential along the vertical direction of the silicon film. The...
An analytic surface potential based non-charge-sheet model for poly-silicon thin film transistors (poly-Si TFTs) is proposed in this paper with consideration of the substrate and film thickness effects. The 1-D Poissonpsilas equation with dopant, mobile, and the trap charge terms is first solved to obtain accurate yet continuous channel potentials physically. An analytic non-charge-sheet drain current...
A global continuous channel potential solution is proposed for the modeling of symmetric double-gate (DG) MOSFETs. To obtain the channel potential, from accumulation to inversion regions, 1-D Poissonpsilas equation in the silicon film of the DG MOSFETs is solved physically. The extensive comparisons between the calculated results and numerical simulations illustrate that the analytical solution is...
We have fabricated active-matrix organic light emitting diode (AMOLED) test arrays on an optically clear high-temperature flexible plastic substrate at process temperatures as high as 285 degC using amorphous silicon thin-film transistors (a-Si TFTs). The substrate transparency allows for the operation of AMOLED pixels as bottom-emission devices, and the improved stability of the a-Si TFTs processed...
In this paper, we discussed the humidity sensing behavior of Zinc Oxide modified porous silicon (ZnO/PS) composite structure. The porous silicon substrates were prepared by the electrochemical etching process first. Then, by sol-gel technique, it is possible to obtain a uniform Zinc Oxide films on the porous silicon substrates. The electrical conductivities of the porous silicon and Zinc Oxide modified...
In this paper, a relative humidity sensor based on zinc oxide modified porous silicon was discussed. The porous silicon was prepared by electrochemical etching process first. Then the sol-gel precursor of Zinc Oxide was applied to the PS substrates and annealed at 450 degC. By this technique, it is possible to obtain a uniform zinc oxide film on the porous silicon substrates. The electrical conductivities...
