Abstract
⺠The article describes methods how to prepare, characterize and clean ultrasharp tungsten tips. ⺠A novel method for estimating the tip radius based on a single measurement of autoemission current is described. ⺠MCFRW (Monte Carlo Floating Random Walk) method is used to calculate an electric field in proximity of the tip apex. ⺠The most frequently used tip cleaning procedures are investigated. ⺠Effectiveness and optimal cleaning conditions are discussed for each of the methods.
