Tóm tắt
With a collection of images taken with the scanning tunneling microscope from the samples of several different organic and biological molecules adsorbed on graphite and/or gold substrates and covered with a very thin layer of 50% glycerol–water solution we show that covering such samples with the solution could facilitate imaging of them and improve the quality of images thus collected, and very often images with atomic resolution could be obtained.
