    How does annealing improves the ohmic contact?

    Thanks for your reply zz. That definitely is true. Here materials does not matter here since I am asking the temperature dependence of the barrier potential right? Only numeric here would be work functions (work function of a metal> work function of the semiconductor) - meaning they should make...

    How does annealing improves the ohmic contact?

    OK just made a typo.. Corrected. Still question remains. What is the effect of temperature ?

    Electrons have to move -- why?

    Lets think of it as a person who wants to watch a movie on the couch vs exercise in the gym. Couch is a low energy state and most people want to be there, If any external energy is given than a person might want to get out and exercise. Electrons are the same way, they want to be on the low...

    How does annealing improves the ohmic contact?

    Suppose we have a p-type material and metal contacts deposited taking the work function of a metal and semiconductor into account. At room temperature (depending on the doping level) they might now show non-linear IV curve (non-ohmic behavior). How does annealing at higher temperature improves...

    How to avoid lab during PhD thesis writing

    No worries, I am sorry If I overreacted. We talked with Prof and looks like It will be OK in the end. I decided to take everything a little more easy , doing my best and leaving the rest to him :) Thanks for your comments.

    How to avoid lab during PhD thesis writing

    Our school have 3 steps. Qualifiers, comprehensive and thesis. Thesis is only 2 weeks before the defense. I have no idea you assume all the universities need to have 6 weeks before the defense and the thesis submission. In our case, we submit most of it in comprehensive and there is some to add...

    How to avoid lab during PhD thesis writing

    ZapperZ, thanks for getting my point. gleem and Choppy. If I am working in the lab day and night ? when do you think I get ready for my defense?! I am not magic. I am a human. This is when I need time to get ready. "what are you doing now? not much" I am surprised how you can ask this...

    How to avoid lab during PhD thesis writing

    Hello I will defend in a couple of weeks and I have been asked to do experiments that are not directly adding to my thesis (I can force it and add If I wanted but not really critical). Normally PhD candidates in the final stage are given a time to work on their PhD thesis and in my situation...
