You Are Encouraged To Ask Your Tutors And Peers For Help In Completing The Coding In 3329428

Name: U-number: Follow the instructions and enter your results into this document, then convert to pdf and submit on Wattle. You are encouraged to ask your tutors and peers for help in completing the coding in the Assignment but you MUST answer the questions on your own. The questions will require you to engage in independent investigation to describe trends in the data and the underlying physics. You should use multiple, high quality sources, synthesize the information, and paraphrase it. Make sure you reference your sources, using IEEE format (see Wattle/Assignments tab). If you engage in plagiarism by copying something from a textbook, internet source, or your peers you will be given zero marks for that question, and you will be investigated for Academic Misconduct. If you are not clear what is required to avoid Plagiarism, please see the Paraphrasing and summarising resources provided by the ASLC in Writing and referencing resources on the ASLC Turnitin practice site: http://www.anu.edu.au/students/learning-development/academic-integrity/turnitin The Haynes-Shockley experiment Read the extract from Schroder that is provided on Wattle [Chpt. 8, pg 482-484, Schroder, ‘Semiconductor material and device characterisation’, 3rd Ed., IEEE Press, Wiley Interscience, 2005]. The notation introduced in this extract will be used without definition throughout the instruction sheet. Download the file A1_2.zip in A1.2 UG and PG on the Assignments tab of the Wattle page. Save it in a folder somewhere. Open the A1_2.mat file in Matlab and run the code. This Matlab program calculates change in the minority carrier concentration at the collector as a function of time. The experimental parameters and material properties have been chosen so that it will output a figure similar to Fig.8.15 (b), except we are plotting ?n(x=d,t) instead of a normalised value ?n(x=d,t)/ ?n(x=d,t=0). Take a few minutes to look at the code and identify equation 8.35 in the Schroder reference. 1. Keeping all the same experimental and material parameters, vary d from 50-100 um to explore how the pulse shape varies at different points between the contacts (try at least 3-4 different values). 2. Plot ?n(x,t) for the different d values on one graph. • if you comment out close all at the start of the code, you can plot your calculated data sequentially on the same graph. • You can use Matlab plot tools to edit and label your graph: http://au.mathworks.com/help/matlab/creating_plots/plotting-tools–interactive-plotting.html;jsessionid=cdf29cdfb7ae8486218a3e8373e6?searchHighlight=edit
