The Level II STM classroom course also underwent a makeover that was more cosmetic than a revision.
In addition to changes for the three primary STM training courses, two new required continuous learning modules (CLMs) have been added to the two existing required CLMs, CLE 021 (Technology Readiness Assessments, for Level II) and CLM 014 (IPT Management and Leadership, for Level III).
31 Physical Review Letters, the duo described using a sensitive photomultiplier tube and lenses to collect light from a metal sample as it was scanned with the STM tip.
Both Ho and Gimzewski have conducted experiments exploring the mechanical effects of STM tunneling current on molecules.
But without some immediate feedback from the physical features of the landscape, a scientist operating the magic wrist would have a hard time guiding the STM tip to specific locations on a sample.
To help scientists correlate the feel of atomic landscapes with the visual appearance of STM images, the IBM team plans to program an auxiliary computer to display images of sample surfaces that also show the path of the tip as it was steered by the teleoperator.
