In addition to revolutionary, theoretical concepts of quantum physics (take, for example, research from the Institute for Quantum Studies), cutting-edge technologies are also a requirement for further developing this distinguished field.
Recently, our laboratory added the multipurpose deposition system shown here, combining five magnetrons (both DC and RF, plus ion assistant deposition), electron guns, thermal evaporators, and an effusion cell. Coupled with our e-beam lithography system (shown next), we've created a powerful tandem for contributing to, and advancing, quantum device research.
While APL devices may look expensive, not all of our instruments have been purchased brand new. The faithfully reliable wirebonder shown above was restored to working order by our own effort. So, rather than spending an immoderate $20,000 on new equipment, we conserve our budget considerably with a little patience and technical ingenuity. Dozens of similar examples in our lab help demonstrate APL's conscious efforts to recycle and re-use machinery and equipment, not just to control costs, but also to minimize impact on the environment.
Donated by Mr. Larry Glassman, a pioneer of digital signal acquisition in electron microscopy. We restored it to working condition ourselves, after its long journey from Atlanta, Georgia.
This scanning electron microscope is reserved for experimentation with e-beams (which was how the Aharonov-Bohm effect was detected) and for training students.
Collaborating with our outstanding colleagues, combined with a steady accumulation of cutting-edge technologies in our first-rate facility, creates for us a powerful tandem of potential for contributing to, and advancing, quantum device research.
