We have devised a "square micro-four-point probe method" using an independently driven ultrahigh-vacuum four-tip scanning tunneling microscope, and succeeded for the first time to directly measure anisotropic electrical conductance of a single-atomic layer on a solid surface. A quasi-one-dimensional metal of a single-domain Si(111)4 x 1-In had a surface-state conductance along the metallic atom...
Aim: We assessed the safety and efficacy of three different local anesthesia methods (pudendal nerve blockade, tenoxicam suppository and rectal lidocaine gel) before transrectal ultrasound (TRUS)-guided biopsy of the prostate in this study. Materials and Methods: In our prospective and controlled study, 136 consecutive patients were randomized into four groups: men in group 1 (n=41) received no...
We present a four-probe setup for measuring temperature of Joule-heated silicon in two independent ways from the same voltage measurement: method using thermal dependence resistivity and based on measured sheet power density. The methods are compared to optical measurements made by fitting gray-body model onto data commercial spectrometer. conducted 890 K 1540 K, they converge at temperatures a...
