Abstract:
A semiconductor element, comprising:a source region, a drain region, a channel forming region connection said source region and said drain region and a gate applying an electric field to said channel forming region, and a carrier confinement region isolated by said channel forming region and by a potential barrier between said channel forming region and the carrier confinement region, wherein said carrier confinement region is formed of a grain comprised of a conductor or a semiconductor and is disposed between said channel forming region and said gate and is surrounded by an insulator, wherein said carrier confinement region is smaller in width than said gate and wherein said grain size of said carrier confinement region has a diameter of no more than 10 nm and wherein a capacitance around said carrier confinement region is no more than 1 aF.
