Y. Han, J. Y. Zhu, Feng Liu, Shao-Chun Li, Jin-Feng Jia, Yan-Feng Zhang, Qi-Kun Xue
2004 Physical Review Letters  
We show that a charged mesa, due to its reduced chemical potential, acts as a Coulomb sink and grows at the expense of neighboring neutral mesas.  ...  We propose the concept of a "Coulomb sink" to elucidate the effect of Coulomb charging on coarsening of metal mesas grown on semiconductor surfaces.  ...  So, the amount of growth scales with in a 1=3 power law and with Q 0 in a 2=3 power law.  ...

The time required for the fabrication is much smaller in comparison with the standard method of ion milling. The process used is controllable which provides acceptable precision of mesa fabrication.  ...  The technology of wet etching allowing fabrication of standalone BiSrCaCuO mesa structures was proposed. The produced mesas can be produced much thicker than ones usually being studied.  ...  The etching was monitored visually and stopped with the disappearance of most of the flakes not covered with photoresist. The result of the cross-cut etching with unremoved PR is shown in Fig. 1b .  ...
