Thesis / Student Research Project:"Investigation of high electric field degradation effects on the nanoscopic electrostatic drive actuators (NED)" (IPMS-2018-131)
The electrostatically driven MEMS based NED-actuators are the patented new class of lateral electrostatic bending actuators, which have advantages compared with a classical electrostatic drives. Thanks to a small electrode gaps even moderate voltages create high homogeneous electric fields of MV/m range. Locally the electric fields due to geometry variation or processing tolerances are highly inhomogeneous and can reach values of tens to hundreds of MV/m. This could cause negative effects for the actuator, performing its degradation and reduce its lifetime. The aim of this work is to investigate and to evaluate the effect of high electric fields on narrow gap electrostatic systems with Si electrodes.
Acquaint oneself with the possibilities of Nano e-drive technology
State of the Art regarding high field degradation mechanisms (cold Si-corrosion, ion migration, field emission, etc.) of silicon based MEMS
Investigate the potential degradation mechanisms occuring on the NED-Actuators
Characterization of test structures under high e-fields
Analyze the e-field impact on the evolution of the degradation and comparison with state of the art
