    MPhys in the USA? How do I pick a specialty?

    Here's an non-US suggestion. First of all, being at Leicester I imagine that you have (or had) an interest in space exploration as well as pure physics/planetary science. I would suggest that you do change to the BSc and do a separate MSc, not least because of the following. If you have an...

    Depletion depth in a PIN diode

    Ok. Thanks very much. I'll look for that book. I've never heard them called P \pi N before (just non-ideal PIN or PPN (& PNN))! Cheers. FWIW, they're experimental diodes from another lab we're reverse biasing and using for X-ray spectroscopy rather than their original purpose. I'm trying...

    Depletion depth in a PIN diode

    Thanks marcusl! What do you do when you don't have an ideal I layer? For example, I have some diodes here where the I layer isn't really undoped, but rather it has an unitentional doping (~1016 cm-3 (P type), compared with ~1018 cm-3 for the P and N layers). The I layer is still << doped...

    Depletion depth in a PIN diode

    Hi guys, I'm trying to find a reliable formula for calculating the depletion depth in a PIN diode at a given voltage and knowing the doping of the layers. Does anyone have one? Formulae for the PN diode are common, but don't apply to the PIN directly as far as I can see. I found a formula...
