Probing the Intersection of Nanotechnology and Biology

Presenter at NanoScientific Symposium at SUNY Polytechnic Nov. 19-20, 2019

Dr. Nathanial Cady, Professor of NanoBioscience, SUNY Polytechnic Institute

 

Prof. Cady obtained his Ph.D. in Microbiology from Cornell University in Ithaca, NY. He is currently a professor of nanobioscience in the College of Nanoscale Science (SUNY Polytechnic Institute). Prof. Cady has active research interests in the development of novel biosensor technologies and biology-inspired nanoelectronics, including novel hardware for neuromorphic computing.

Biology and nanotechnology may appear to exist at distant ends of the spectrum, within the world of science and technology. At its core, however, biology is a nanoscale science, one in which molecular events govern how cells grow, how organisms function, and how organisms interact with each other. On the other hand, we can gain helpful insights and inspiration from the biological world as we develop engineering solutions at the nano, micro and macro size scale. In my research group, we leverage nanotechnology to improve our understanding of biological systems, and leverage biological innovations to design and fabricate unique nanotechnologies. As part of this work, we often need to measure the size, shape, and mechanical properties various systems. In the field of microbiology, we have developed microfluidic platforms that enable us to grow cells in controlled environments and then monitor their morphological and physical properties using integrated confocal microscopy and atomic force microscopy. We have extended this technology to the study of higher organisms, including measuring the mechanical properties of mammalian tissues and tissue development. These projects demonstrate the power of using nano and micro technologies for the study of biological phenomena. Beyond this work, we are also exploring how biological systems can be emulated in nanoelectronics. We are developing nanoscale electronic devices called memristors that mimic the function of neural synapses in the human brain. As part of that work, we perform extensive characterization of materials and devices, including cutting edge metrology techniques.

He is also active in the IEEE Electron Devices Society (EDS) serving in various technical committees including IEDM.

 

Nanoscale Vacuum Channel Transistor on Silicon and Silicon Carbide

Long-term operation in the harsh environment becomes increasingly less sustainable due to several device aging mechanisms. Total ionizing dose (TID) and displacement damage (DD) degradation limits the new class of missions including long term (> 20 years) deep-space exploration, nano-spacecraft, Europa mission, and so on. In order to tackle such challenges, in this talk, we propose a nanometer scale vacuum channel transistor that combines the advantages of both vacuum and solid-state electronics, providing compactness as well as high performance.

Our fabricated vacuum channel transistor is introduced and the radiation immunity is experimentally assessed. Incident radiation needs to traverse some distance in the channel to release its energy and liberate electrons from the semiconductor for device degradation to occur. Therefore, the only approach to completely avoid the radiation effects is to utilize a vacuum channel. Unfortunately, as long as the electron emitter and collector structures exist, the vacuum transistor faces mechanical reliability issue associated with the electrode material rupture and degradation in the long term. Our latest results on SiC-based nanoscale vacuum channel transistor suggest them to be a robust alternative to silicon-based vacuum devices.
