Homework Help: Device physics problems

  1. May 11, 2008 #1
    Why does electric field in MOS device tend to increase as device dimension
    shrink

    describe the cross-section of a MOSFET with short channel showing the charge
    sharing phenomenon

    can anyone help me to find out these two problems?
    I could not find them out from the book

    has a proper treatment of the short channel effects and what happens when the channels are reduced.

    basically, both issues are interlinked and is a bit long winded for here....
