InP/GaAsSb Double Heterojunction Bipolar Transistor Technology with f(MAX)=1.2 THz
(2021)2021 IEEE International Electron Devices Meeting (IEDM)Transistor (DHBT) emitter fin architecture with a record fMAX = 1.2 THz, a simultaneous fT = 475 GHz and BVCEO = 5.4 V. The resulting BVCEO × fMAX = 6.48 THz-V is unparalleled in semiconductor technology. The performance arises because the process allows: i) an optimal choice of baseemitter access distance down to 10 nm, ii) the use of thicker base contact metals, and iii) the minimization of parasitic capacitances and resistances via ...Conference Paper -
Formica Forma: Explorations in Insect-Robot Collaboration for Emergent Design and Manufacturing
(2021)Distributed Proximities: Proceedings of the 40th Annual Conference of the Association for Computer Aided Desing in Architecture. Volume 1: Technical Papers, Keynote ConversationsHybrid robot systems that cooperate with live organisms is an active area of research, in part to leverage biological advantages such as adaptivity, resilience, and sustainability. Formica Forma explores new possibilities of codesigning and cofabricating in partnership with Western Harvester ants to build forms that would be challenging with industrial techniques. Using a robotically controlled UV light (350–405 nm) as an environmental ...Conference Paper -
Parametric Approach to Simplified Life Cycle Assessment of Bamboo Frame Buildings
(2021)The provision of sustainable housing solutions is one of the main challenges in emerging economy countries. Furthermore, it is clear that a sustainable solution should be based on renewable bio-based materials. The scientific and practical evidence clearly suggests that the use of bamboo in the provision of housing solutions not only brings environmental but also socio-economic benefits to the communities using these strategies. One barrier ...Conference Paper
