First papers on AC-TEM report on results obtained with 200 kV TEMs, redeemed by papers obtained with 300 kV TEMs. Since 2006, papers with 20-80 kV are published. In all voltage ranges, the number of publications using aberration-corrected electron microscopy is strongly increasing. Today, the ratio of publications that use 20-80 kV; 100-200 kV; 300 kV is 30%; 40%; 30%.
