The phenomenon of impact-ionization is proposed to be leveraged for a novel biosensor design scheme for highly efficient electrical detection of biological species. Apart from self-consistent numerical simulations, an analytical formalism is also presented to provide physical insight into the working mechanism and performance of the proposed sensor. It is(More)
Power law time-to-breakdown voltage acceleration is investigated down to ultra-thin oxides (1.1 nm) in the ESD regime in inversion and accumulation. Breakdown modes, oxide degradation and device drifts under ESD-like stress are discussed as function of the oxide thickness. The consequent impacts on the ESD design window are presented. 2009 Elsevier Ltd. All(More)
A gas-sensor based on tunnel-field-effect-transistor (TFET) is proposed that leverages the unique current injection mechanism in the form of quantum-mechanical band-to-band tunneling to achieve substantially improved performance compared to conventional metal-oxide-semiconductor fieldeffect-transistors (MOSFETs) for detection of gas species under ambient(More)
Verification of ESD safety on full chip level is a major challenge for IC design. Especially phenomena with their origin in the overall product setup are posing a hurdle on the way to ESD safe products. For stress according to the Charged Device Model (CDM), a stumbling stone for a simulation based analysis is the complex current distribution among a huge(More)
