Physical samples group instrument and characterization data from the same run together for comparison and analysis. You can think of a physical sample as the central organizing unit for a single experiment or growth.

​
Associations

Each physical sample can be linked to the following:
AssociationRelationshipDescription
Growth InstrumentOptional, oneThe synthesis instrument used for this growth (MBE, PVD, CVD, etc.).
Target MaterialOptional, oneThe material being grown, including substrate and layer definitions.
ProjectsMany-to-manyPhysical samples can belong to multiple projects.
Data ItemsOne-to-manyIndividual files (RHEED, XPS, SEM, etc.) linked to this physical sample.
NotesOptional, oneFree-form notes that auto-save as you edit.

​
Creating a Physical Sample

When creating a physical sample, you provide:
  1. Sample Name (required): a descriptive name for the growth run
  2. Growth Instrument (optional): select from instruments configured in Metadata
  3. Target Material (optional): select from materials configured in Metadata
  4. Notes (optional): goals, remarks, processing conditions, or other context
After creation, you can link data items to the physical sample from the Data page by setting the Physical Sample column on each data item.

​
Detail Page

The physical sample detail page shows:
  1. Header: editable name with a “Physical Sample” badge
  2. Metadata bar: last modified date, growth instrument, target material, project assignment, and owner
  3. Notes: auto-saving free-form text
  4. Data Items: a list of all data items linked to this physical sample, with a count badge and a link to add more from the Data page
  5. Analysis Results: a chart aggregating processed results across all linked data items
  6. Similarity: explore how this physical sample’s data compares to others in your organization
