"This document contains BNL procurement requirements specifications for solicitation and technical evaluation.

The information is high-level and does not include the details necessary for "development" or ''production" as defined under 15CFR § 772.1, 22 CFR §120.33, or 10 CFR Part 810; therefore, it does not constitute export-controlled technology or technical data."

Project Objective

The Center for Functional Nanomaterials (CFN) will partner with the contract to build a low-temperature (LT) scanning probe microscope (SPM) using an existing cryostat. The LT-SPM will be integrated into the existing multiprobe ultra-high-vacuum (UHV) surface analysis system at CFN. Integration of the LT-SPM with the existing room-temperature to high-temperature STM (RT–HT STM) will extend STM operation over a temperature range from approximately 5 K to 500 K and will add new capabilities, including atomic force microscopy (AFM) and electrical transport measurements at ~5 K.

These enhancements will provide significant new capabilities for the user and scientific communities, particularly in quantum information science (QIS), nanoscience, two-dimensional functional materials research, and surface science. The project is designed to preserve all original functionalities and capabilities of the system that have demonstrated excellent performance, ensuring that none of these are compromised or sacrificed, and avoiding any prolonged system shutdown that would impact the user community.

Project Scope This SOW covers the following activities.

• Single -atom positioning precision

Performance

• High repeatability under low-temperature UHV conditions

• < 1 pm Z noise: enables stable imaging and manipulation feedback at atomic resolution

• < 0.02 nm/h XY drift: allows controlled repositioning of individual atoms over time without drift smearing atomic sites.

• Sub-nanoamp-to-femtoamp tunneling current sensitivity: critical for atomic manipulation protocols that rely on controlled tip–sample electronic interaction.

• QPlus AFM oscillation amplitude ~10 pm achieved: supports combined force and tunneling based manipulation with high force sensitivity.
