Abstract
We report on low‐energy electron microscopy imaging of ferroelectric domains with submicron resolution. Periodic strips of ‘up’ and ‘down’‐polarized ferroelectric domains in bismuth ferrite – a room temperature multiferroic – serve as a model system to compare low‐energy electron microscopy with the established piezoresponse force microscopy. The results confirm the possibility of full‐field imaging of ferroelectric domains with short acquisition times by exploiting the sensitivity of ultraslow electrons to small variations of the electric potential near surfaces in the “mirror” operation mode. magnified imageKeywords
