IBM System Storage Ideas Portal


This portal is to open public enhancement requests against IBM System Storage products. To view all of your ideas submitted to IBM, create and manage groups of Ideas, or create an idea explicitly set to be either visible by all (public) or visible only to you and IBM (private), use the IBM Unified Ideas Portal (https://ideas.ibm.com).


Shape the future of IBM!

We invite you to shape the future of IBM, including product roadmaps, by submitting ideas that matter to you the most. Here's how it works:

Search existing ideas

Start by searching and reviewing ideas and requests to enhance a product or service. Take a look at ideas others have posted, and add a comment, vote, or subscribe to updates on them if they matter to you. If you can't find what you are looking for,

Post your ideas

  1. Post an idea.

  2. Get feedback from the IBM team and other customers to refine your idea.

  3. Follow the idea through the IBM Ideas process.

Topological Surface States Atomic Layer Deposition for Selective Ion Sensors

PROBLEM: An ALD oxide over a topological sensor surface can tune which ions reach the binding layer, yet the oxide may also alter the protected conduction channel that carries the signal. A sensor calibrated after one oxide recipe may therefore behave differently after a recipe change, and the calibration history can be lost when recipes are overwritten. Sensor teams need preserved copies of each oxide and calibration pairing.

SOLUTION: Storage Copy Data Management would keep versioned copies of topological ALD sensor designs, preserving each oxide recipe, biosorbent batch, and calibration set as a governed copy. A new recipe would create a new copy rather than replacing the old one, so signal changes can be traced to a specific ALD build. It manages copies, not selectivity.

EVIDENCE BASIS: DOCUMENTED as physics — Topological surface states are conducting surface/edge states protected by band topology (Nobel 2016); catalytic application is REPORTED/emerging; DFT (Kohn–Sham) predicts which surface groups bind which ions; biosorption validation uses batch isotherms. Source: Nobel Prize in Physics 2016; Hohenberg–Kohn 1964; Kohn–Sham 1965.
