Field emission in micro vacuum devices
Sviðsröfun (e. field emission) liggur til grundvallar björtum rafeindageislum, en þeir eru nauðsynlegir í hvers konar hátækniferlum til dæmis örrásaframleiðslu, smásjártækni og við framköllun aflmikilla örbylgjugeisla. Sviðsröfun byggir á því að utanaðkomandi rafsvið aflagar yfirborðsmætti milli …

High resolution simulation of a vacuum microdiode
In this thesis a vacuum microdiode is simulated where each electron in the system is regarded as point charge and observed through the system from Cathode to Anode. A space charge limited emission process is simulated. Low voltage sufficies to create large electric field across the vacuum diode …
