Pi. Arseyev et al., PROBLEMS OF LOW-TEMPERATURE STM APPLICATION TO THE HIGH-TEMPERATURE SUPERCONDUCTORS INVESTIGATION, PHYSICS OF LOW-DIMENSIONAL STRUCTURES, 5-6, 1997, pp. 131-140
In the present paper we discuss the main aspects of low temperature (L
T) STM/STS investigations of high-temperature (HTc) superconductors (S
C). STM/STS images of Bi2Sr2CaCu2O8+d were obtained by home-built tunn
eling microscope with in situ sample cleavage specially developed for
operating in the He temperature range. Our experimental results can be
treated in the framework of new theoretical models of tunneling proce
sses in nanometer scale junctions.
