RHEED Image Contest

What:

We are having a contest for RHEED Image Library (RIL) submissions. Since 2012, this database has offered kSA 400 customers reference RHEED images and RHEED movies for over 110 different materials systems. With the RIL, customers can compare their RHEED images to those from other users, perform real-time analysis on RHEED movies simulating live acquisition, and explore new material systems.

For example, you can:

  • Compare your oxide-desorbed Si (100) surface with that of others.
  • Test the ratio of InP [110], [100], and [112] streak spacings to see how well they correspond to the expected values.
  • Discover what a 150 Angstrom layer of lattice mismatched InGaAs grown on GaAs looks like. See if you can see the layer relaxation in a recorded movie.
  • Examine how the Sb overpressure impacts your GaSb RHEED reconstruction pattern.
  • Compare RHEED images for various oxides (LaBaCuO, LaCoO3, SrFeO3, etc.) grown on SrTiO3.

Why:

We want to increase the size and usefulness of our RHEED database, and we need your submissions to do so. As an added incentive, we are offering the following prizes for valid submissions:

  • Amazon Echo or Google Home device with submission of 15 images and/or movies*
  • An Apple or Android smart watch with submission of 30 images and/or movies*

We hope you will help us expand our RHEED database (even if your employer’s policies do not allow you to accept gifts). We know that it takes time to generate such submissions, but we’ll take as many or as few images or movies as you’re willing to give us!

When:

The last day to submit your images/videos for this offer is October 9, 2019.

We expect to have the next version of the RHEED database available to kSA 400 users by December 4, 2019.

Where:

If you would like to participate, simply email us at [email protected] (subject line: RHEED Image Database Project), and we’ll send you a unique username and password for uploading files to our secure FTP site. In your email, please let us know if you would like us to include any customer contact or customer facility information with your files, or if you would prefer to simply remain anonymous.

Prizes:

We are offering the following prizes for valid submissions:

  • Amazon Echo or Google Home device with submission of 15 images and/or movies*
  • An Apple or Android smart watch with submission of 30 images and/or movies*

*To be eligible for these prizes, all images and movie files must include full description of image conditions, such as substrate temperature, substrate material, film information, film thickness and growth rate if applicable, crystal orientation (e.g. (100) surface along a [110] direction), and electron gun energy.  The submission must also provide at least 3 different surface materials (e.g. InGaAs on GaAs, GaAs 2×4 reconstruction, AlGaAs on GaAs). Images must be in kSA400 .img format, and movies must be in kSA400 .imm format. All images and movie files are subject to kSA approval and must be good quality. Prizes are available to every kSA400 customer who meets the above criteria. Limit: 2 prizes per customer. The last day to submit your images/videos for this offer is October 9, 2019.
