Image of the Month


We have lots of people in the EMU who are acquiring lovely images and great data. If you have an image that you think is good, please submit it to the EMU image of the month competition*. The prize is a $50 gift voucher from the UNSW book store. All submissions are voted on by EMU staff. Your winning entry will be displayed in the EMU and put onto our website.

To enter email your image to us in .tif format with:

  • a brief description (2 - 3 sentences)
  • your full name and your school/department
  • your supervisor's name
  • the microscope (and technique) that you used

*Only one submission per person per month.

*Each person may only win one prize each calendar year.

This SEM image shows the cross-section of a silicon solar cell TEM sample prepared the using in-situ liftout technique. Top side is a 3um thick Pt later deposited on top of silicon wafer in order to protect the surface morphology, bottom side is the silicon substrate. When transferring the micro-sized sample from its original place into sample grids, people need to weld sample by Pt deposition. The deposition current is too high so excessive local heat recrystallize the Si sample and re-shape the top Pt layer into micro/nano-spherical structure.

This image shows the surface structure of rice bran that has been treated with Ultrasound at maximum amplitude. The rice bran surface structure has become very porous.  Distribution of resistant starch particle has also observed in the porous structure.

This image shows a gold particle (~50 nm in size) sitting on top of a piece of ultrathin gold nano-sheet of ~5 nm in thickness. The weight of the particle causes local bending of the sheet, which induces a “spider web” like pattern under scanning transmission electron microscopic imaging.

This image shows the interface between GaP and ZnS, which were grown as a multilayer film on silicon.  The interface between GaP and ZnS hosts infinitive three-dimensional (3D) defects such a plan of vacancies and dislocations or a plan of twinning. A considerable enhancement of photoactivity is found at multilayered structure containing plenty of twin boundaries compared with twin-less samples using a new definition of “Twin boundary engineering”.

The image shows uniformly-sized ordered Pt3Sn cubes and right bipyramids mainly bounded by (100) facets. The pyramids provided the flexibility of the way particle assemble, breaking the stern 90 degrees given by the sub-10 nm nanocubes forming all kinds of curved pattern.
