The fact that the universe is made entirely out of matter, and contains no free anti-matter, has no physical explanation. The unknown process that created matter in the universe must violate a number of fundamental symmetries, including those that forbid the existence of certain electromagnetic moments of fundamental particles whose signatures are amplified by the large internal fields in polar molecules.
Photonic integrated circuits have experienced a tremendous progress over the last decade, seeding a commercial photonic chip ecosystem, which provides active and passive photonic chips with well-defined circuit components. Indeed, one of the first photonic chip materials was lithium niobate, which has been used for decades for high-speed modulators, underpinning the internet, and as a nonlinear optical material for frequency mixing processes.
Interferometers can very accurately detect very small variations of physical parameters like displacement, temperature, strain, etc. Integrating them on a silicon chip can dramatically increase their presence in the market due to cost and size reduction.
Beta-Gallium Oxide is an emerging ultra-wide band gap semiconductor with a predicted critical breakdown field much higher than the commercial wide band gap semiconductors such as Gallium Nitride and Silicon Carbide. The key attractive feature is the availability of single crystal large area bulk substrates. This talk will begin with the motivation for pursuing research on ultra-wide band gap semiconductors for applications in power electronics. Key results in epitaxial growth and device performance will be highlighted.
The explosion in energy consumption from microelectronics – due to the increasing reliance on Internet of Things devices, Artificial Intelligence, and Data Centers – is projected to exceed 20% of worldwide electricity production by 2030 and its current exponential growth would exceed global energy production by 2050 if left unchecked. These era-defining energy challenges not only require physical breakthroughs which drastically reduce the energy cost of information processing, i.e.
Please join us for an exciting talk from leading Industrial Ecologist, Professor Roland Geyer, who will be speaking about the content of his new book.
An expert on U.S. energy policy, Jay Hakes has a long history of working on
energy issues, including as Administrator of the U.S. Energy Information
Administration during the Clinton administration and as Director for Research and
Policy for President Obama’s BP Deepwater Horizon Oil Spill Commission. He also
served for thirteen years as the Director of the Jimmy Carter Presidential Library.
