I'm writing a lab report for a series of experiments on GaAs wafers related to dopants and dopant quantities. For the lab report it is expected to include a few diagrams and figures. I've been wanting to put a hall-bar into a set of circuit diagrams for this purpose. I want said component to be repeatable, that is I want to be able to call it in tikz or circuitikz figures by use of - for example - the command \Hallbar. I discovered circuitikz yesterday (I'm not an electronics student, more along the lines of materials technology) and so am very new to it, but this is what I have concocted so far:
Code: Select all
\documentclass{minimal}
\usepackage[european]{circuitikz}
\begin{document}
\newcommand{\incHB}[0]{10}%Constant to define the size of the hall-bar
\def\Hallbar{%
+(0mm,0mm)-- +(1.0mm*\incHB,0mm*\incHB) -- +(1.0mm*\incHB,1mm*\incHB) -- +(1.5mm*\incHB,1.0mm*\incHB) -- +(1.5mm*\incHB,0mm*\incHB) -- +(3mm*\incHB,0mm*\incHB) -- +(3.0mm*\incHB,1.0mm*\incHB) -- +(3.5mm*\incHB,1mm*\incHB) -- +(3.5mm*\incHB,0mm*\incHB) -- +(4.5mm*\incHB,0mm*\incHB) -- +(4.5mm*\incHB,-0.8mm*\incHB)
+(0.0mm*\incHB,0mm*\incHB) -- +(0.0mm*\incHB,-0.8mm*\incHB) -- +(1.0mm*\incHB,-0.8mm*\incHB) -- +(1.0mm*\incHB,-1.8mm*\incHB) -- +(1.5mm*\incHB,-1.8mm*\incHB) -- +(1.5mm*\incHB,-0.8mm*\incHB) -- +(3mm*\incHB,-0.8mm*\incHB) -- +(3.0mm*\incHB,-1.8mm*\incHB) -- +(3.5mm*\incHB,-1.8mm*\incHB) -- +(3.5mm*\incHB,-0.8mm*\incHB) -- +(4.5mm*\incHB,-0.8mm*\incHB)
}
\begin{circuitikz}
\draw (0,0) \Hallbar;
\end{circuitikz}
\end{document}Yet I wonder, how do I define contact points on the hall-bar so that I can use them in relations to other components/circuitry with a minimal amount of fuzz? It has, as you may surmise, 6 contact points for measurement and application of E-field. As it is I'd have to define coordinates manually for all the contact points. Which is going to be a pain if and when the circuitry needs changing once first drawn.
Thank you for any help you can give!
