What is break-junction technique for molecular electronics? briefly explain the procedures of the technique. how can we control the electrode gap in it? can we use steel as substrate for it? why? when we measure the conductance of benzene-1,4- dithiolate molecule using break-junction technique, how can we judge the point when a single molecule is connecting two gold electrodes
