A Comprehensive Oxide-Based ReRAM TCAD Model with Experimental Verification

Abstract—During the last few years, oxide-based ReRAM technology has attracted intense industrial and scientific research interest. Therefore, we have performed an in-depth computational study with a focus on data retention besides the resistive switching and the current run-away. Our newly developed comprehensive TCAD (Technology Computer Aided Design) model provides deep insight into the underlying microscopic processes and is validated against experimental data as an accurate and predictive simulation tool.

An Introduction to Meshing in Victory Process

Victory Process (VP) uses two types of mesh to represent the structure: • The geometry mesh, which is used to represent the material regions. • The volume mesh, which is used to represent the volume data (doping etc).

Compact Multi-Level Digital-to-Analog Conversion Using Thin-Film Multimodal Transistors

Unlike conventional ohmic contact thin-film transistors (TFTs), contact-controlled TFTs [1], [2] rely on source energy barriers to produce a range of benefits including: low saturation voltages; extremely high intrinsic gain; power-efficiency; electrical stability; and uniformity of operation, notably with imprecise processes [3]. Generally, these benefits come at the expense of transconductance, however in materials such as polysilicon, similar levels of on-current can be obtained in a more compact footprint without any trace of kink-effect [4], [5].

Investigation and Explanation of PiPiN Avalanche Photo-Diode Characteristics

In this article, the operation of avalanche photo-diodes in the medium gain, continuous operation mode is investigated. In other words, we are not considering diode operation in transient “Gieger” or “single photon” detection mode, but rather in a region safely below secondary breakdown, where a well-designed avalanche photo diode can exhibit a moderate photo-generated current multiplication factor of an order of magnitude or higher.

How do I create complex shapes with fixed cross sections in Victory Mesh?

Victory Mesh versions 1.7.2.C and later include two new commands that can be used for complex shape genera-tion. The path and follow commands can be used together to generate surface meshes of general shapes based on fixed cross sections.PathThe path command connects a sequence of vertices via edges. The command operates in line or Bezier modes. In the line mode the from/to parameters are used to define the start and end of an n-dimensional line segment, for example:
