Keeping Electronics in Line with the Law

Researchers working in part at Stanford Synchrotron Radiation Laboratory (SSRL) beamlines 8-1 and 10-1 recently characterized a promising semiconductor material that could lead to smaller and faster electronic devices of the future. The results are published in Applied Physics Letters.

The famous Moore's Law, which has held true for more than 40 years, says computing power (i.e., the number of transistors on a chip) roughly doubles every 18 months. But traditional electronics using metal-oxide semiconductors are nearing chip design performance limits because the thinner and smaller the components become, the more electric current tends to leak from them, making them inefficient. To keep on top of the curve for smaller and faster electronic devices, new semiconductors must be developed that overcome the limitations of current leakage due to increasingly thin insulating layers.

Using photoemission spectroscopy, Intel researcher Niti Goel of and SSRL scientist Yun Sun successfully measured the alignment of energy bands, or band offsets, between lanthanum aluminate and indium gallium arsenide for potential use as ultra-thin insulators. Such measurements are important for engineering efficient semiconductors that will work on the ever shrinking size-scales needed for advanced electronic devices.

Don't Get Left in the Cold! Hot Water Outage Planned

SLAC's Central Plant hot water system will be shut down starting on Friday, July 18, to allow for maintenance and construction. The hot water will be restored on Monday, July 21, to the following buildings: 040, 041, 042, 043, 044, 048, 051, and 084. A longer outage (through August 2008) will affect Buildings 003, 024, 026, 031, 033, 034, 050, 082 (Fire Station), 137, and 280.

SLUO Annual Meeting


Save the date! The SLAC User's Organization (SLUO) Annual Meeting will be held on Thursday, September 18, in the Kavli Auditorium.

SLUO is the organization of scientists and engineers involved in particle physics, particle astrophysics or nuclear physics research at SLAC. The organization exists for communication between the users of SLAC facilities and the laboratory on matters of operating policy and facilities utilization; to facilitate the involvement of its members in projects at SLAC; to provide information to its members on matters affecting their relationship to the laboratory; and to promote the utilization of existing SLAC facilities and the approval of new ones.

SLAC Today will publish more information about the meeting as it becomes available.

BIS Requisition System To Be Phased Out

Plans are now underway to phase out the Business Information Systems (BIS) Requisition System and move all of SLAC onto e-procurement in PeopleSoft. Purchasing and the Business Applications group are now ready to roll this out to the rest of the site. Particle Physics and Astrophysics will be the next Directorate to make the transition. We are looking at an aggressive schedule to phase out BIS requisitions by the end of October 2008.

Great strides have been made in Purchasing and the Business Applications group to deploy e-procurement to the rest of the site. To implement this change, Purchasing and Business Applications will work with each Directorate one-by-one to discuss workflow rules, training schedules and more. We will keep the site apprised of our progress as we move forward.

For almost a year now, the Stanford Synchrotron Radiation Laboratory (SSRL) has been successfully using the system. They retired their procurement shadow system last January and all of SSRL's requestors were trained to enter their requisitions directly into the e-procurement system. SSRL requisitions are processed on average four days faster than other requisitions on site.

As many of you are aware, the BIS system is just one step in entering your purchase requisition into the PeopleSoft system. BIS requisitions are printed, then all of the data is manually re-entered into PeopleSoft. Maintaining a duplicate system is both expensive and time consuming to SLAC programmers. Removing this system eliminates double data entry, which results in faster processing time, expedited approvals and fewer data entry errors.
