No Access Journal of Vacuum Science & Technology B 41, 023201 (2023); https://doi.org/10.1116/6.0002272 Silicon gated field emitter arrays have been used as a vacuum transistor to demonstrate a 152 kHz Colpitts oscillator. The transfer and output characteristics of the 1000 × 1000 silicon arrays were measured using a collector placed ≈ 1 mm away with a gate voltage up to 40 V and a collector voltage up to 200 V.

As I’ve grown accustomed to the routines and habits of in-person college life, I have quickly acclimated myself to the standard form of greeting on campus: “Oh hey what’s your name? … Yeah, nice to meet you, what’re you studying? … Yo that’s sick!” A script to recite, nearly verbatim, 10 times a day or more. Although easy enough to plod through, each time I am confronted with this call-and-response, I am stopped dead in my tracks at the second question: What is your major?

In the midst of New York Climate Week, a group of faculty and students from Columbia, Yale, and Tsinghua universities met online to consider “The Role of Universities in Solving Our Climate Crisis.” New Bwogger Mason Cannon reports.
