MEAM Seminar: “Aluminum Scandium Nitride Microdevices for Next Generation Nonvolatile Memory and Microelectromechanical Systems”

September 29 at 10:30 AM - 12:00 PM
Zoom – Email MEAM for Link, peterlit@seas.upenn.edu

Aluminum Nitride (AlN) is a well-established thin film piezoelectric material. AlN bulk acoustic wave (BAW) radio frequency (RF) filters were one of the key innovations that enabled the 3G and 4G smart phone revolution. Recently, the substitutional doping of scandium (Sc) for aluminum (Al) to form aluminum scandium nitride (AlScN) has been studied to significantly enhance the piezoelectric properties and to introduce ferroelectric properties into AlN based material systems. The properties achieved have profound implications for the performance of future…

ESE Seminar: “Evolutionary Adaptations and Spreading Processes in Complex Networks”

September 29 at 11:00 AM - 12:00 PM
Zoom – Email ESE for Link jbatter@seas.upenn.edu

A common theme among many models for spreading processes in networks is the assumption that the propagating object (e.g., a pathogen, in the context of infectious disease propagation, or a piece of information, in the context of information propagation) is transferred across network nodes without going through any modification. However, in real-life spreading processes, pathogens often evolve in response to changing environments or medical interventions, and information is often modified by individuals before being forwarded. In this talk, we will…

ESE PhD Defense: “Orbital angular momentum microlasers: From the first demonstration to ultrafast tunability”

September 29 at 3:00 PM - 5:00 PM
Zoom – Email ESE for Link jbatter@seas.upenn.edu

Orbital angular momentum (OAM) carried by structured vortex light establishes a new information dimension, thereby promising high capacity optical communication and high performance computation in both classical and quantum regimes. Meanwhile, laser is the key driver in the field of optics and photonics over other photonic components. Since its discovery, laser technology has demonstrated strong impacts on a broad variety of applications, especially in today’s information technology supporting fast growing cloud computing and communication. As microlaser plays an imperative role…
