CBr4 Gas Delivery System

The Quantum Nanophotonics Group, part of the Physics Measurements Laboratory, requires a replacement CBr4 Gas Delivery System for carbon doping of MBE grown devices. The existing system, installed in 2011, has failed and is no longer serviceable. The new system must be a low-temperature gas source compatible with UHV and a VEECO GEN10 MBE system, capable of doping GaAs from 1e16 cm^3 to 1e20 cm^3 at 1 monolayer/s, and compatible with VEECO molly software. Key specifications include a sealed, temperature-controlled, and vented cabinet for the CBr4 bottle, heated injection lines to prevent condensation, and closed-loop pressure control with stability under 0.2 mTorr. The system must be an established commercial product, new, and covered by a full manufacturer's warranty, with factory testing and data verification required before shipping. Delivery is expected six months after the order, with on-site vendor installation, uncrating, unpackaging, and setup at NIST-Boulder. Electronic manuals and software are required. The system will undergo acceptance testing for up to seven business days and must include a one-year warranty on parts for the cryostat system.

This Federal Requirements and Specification Document outlines a procurement request by the Physics Measurements Laboratory, Applied Physics Division, Quantum Nanophotonics Group (686.10) for a CBr4 (carbon tetrabromide) gas delivery system. The system is required for the carbon doping of molecular beam epitaxy (MBE) grown semiconductor devices, specifically to support ongoing projects involving single quantum dots. The previous system has failed and is no longer serviceable. Key specifications for the new CBr4 gas delivery system include UHV compatibility, the ability to achieve doping concentrations ranging from 1e16 cm^-3 to 1e20 cm^-3 in GaAs grown at 1 monolayer per second, and compatibility with VEECO molly software and a VEECO GEN10 MBE injector system. Additionally, the system must feature a temperature-controlled gas bottle cabinet, heated injection lines to prevent condensation, and a closed-loop pressure control stability of less than 0.2 mTorr. Only established, non-prototype commercial products with an active field presence and a full 1-year manufacturer warranty are acceptable. Delivery is expected at NIST-Boulder in Colorado within six months of order receipt. The vendor is responsible for on-site installation, including unpacking, equipment setup, testing, and technical training. Preliminary factory testing data must be provided prior to shipping, and final government acceptance is anticipated within seven business days of installation.

This combined synopsis/solicitation (NB686100-26-01989) is a Request for Quotation (RFQ) issued by the National Institute of Standards and Technology (NIST) to acquire a cryogenic system. Conducted under FAR Part 12 as a total small business set-aside, the procurement falls under NAICS code 334413 (Semiconductor and Related Device Manufacturing) with a size standard of 1,250 employees. The government intends to award a firm-fixed-price purchase order using the Lowest Price Technically Acceptable (LPTA) evaluation method. Under Factor 1 (Technical Capability), quotes will be evaluated on an acceptable/unacceptable basis, requiring offerors to provide clear technical descriptions and evidence of meeting all minimum specifications rather than merely restating requirements. Factor 2 (Price) will assess price reasonableness. Key performance and delivery terms require FOB Destination delivery to the NIST campus in Boulder, Colorado, within 26 weeks after receipt of order (ARO). Offers must remain valid for 90 days. Quotes must be submitted electronically to Contract Specialist Deionne Jones at deionne.jones@nist.gov. Submissions must include separate technical and price proposals, a valid SAM Unique Entity ID (UEI), country of origin declarations (with applicable tariff disclosures for foreign-manufactured products), and completed representations regarding delinquent tax liabilities and felony convictions. This solicitation also incorporates standard commercial provisions, including a specific deviation clause addressing DEI discrimination by federal contractors.
