"Quantum accordion" is the winner of September in ProIMAGE Contest 2011

(Nanowerk News) NT-MDT announces the September winner of the ProIMAGE Contest 2011 and the top ten contenders to reach the final.
According to the web-site voting, winner for the month of September became Dr. Dmitry Sviridov, (Russia). He will get $1000 certificate for the scan «Quantum accordion».

AFM image “Quantum accordion” collected 3181 votes. This image was obtained in scanning spreading resistance microscopy (SSRM) mode at -3 V sample dc bias. It represents the near-surface distribution of the electrical properties of the undoped GaInP/AlGaInP multiple quantum well heterostructure cleavage. Quantum well region (7 nm thick GaInP QWs (red) separated by 400 nm thick AlGaInP barrier layers (yellow)) was grown between two AlAs /AlGaAs distributed Bragg reflectors (blue) by metalorganic chemical vapour deposition (MOCVD) on the GaAs substrate. The current value in the QWs was larger than in the barriers due to differences in resistivity and Schottky barrier height at the tip-sample interface.

The TOP-10 best images of September are:
