The­sis / Stu­dent Rese­arch Pro­ject:"Inves­ti­ga­tion of high electric field degra­da­tion effects on the nano­sco­pic elec­tro­sta­tic drive actua­tors (NED)" (IPMS-2018-131)

Work­ing field:

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.

Key Aspects:

  • 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

What you bring:

  • Basic know­ledge in the field of micro­sys­tems or mate­rial sci­ence would be an advan­tage
  • Know­ledge in the fields of elec­tro­sta­tics, elec­tro­dy­na­mics, plasma etc. are desi­ra­ble
  • Know­ledge of working in a labo­ra­tory and metro­logy tech­ni­ques
  • Inde­pen­dent, goal-ori­en­ted and struc­tu­red way of working
  • Enjoy­ment of working in an inter­di­sci­pli­nary team

What to expect:

You will find a large net­work of experts working in an open and col­le­gial envi­ron­ment wit­hin the excel­lent Fraun­ho­fer rese­arch and deve­lop­ment infra­struc­ture. We offer an excit­ing, up-to-date the­sis posi­tion in which you can bene­fit from our expe­ri­en­ced team. Our excel­lent indus­try-rela­ted rese­arch and deve­lop­ment infra­struc­ture pro­vi­des you access to a large net­work of experts. You will become part of an inspi­ra­tio­nal inter­na­tio­nal work envi­ron­ment based on trust, crea­ti­vity and team spi­rit. We bes­tow upon you the res­pon­si­bi­lity for your the­sis pro­ject, ensu­ring you space for auto­no­mous work.

Work is plan­ned to be car­ried out in our office in Cott­bus. The the­sis is awar­ded over a Ger­man part­ner uni­ver­sity accord­ing to the hig­her edu­ca­tion laws of the respec­tive federal state.

Fraun­ho­fer is Europe’s lar­gest app­li­ca­tion-ori­en­ted rese­arch orga­niza­t­ion. Our rese­arch efforts are gea­red ent­i­rely to people’s needs: health, secu­rity, com­mu­ni­ca­tion, energy and the envi­ron­ment. As a result, the work under­ta­ken by our rese­ar­chers and deve­l­o­pers has a signi­fi­cant impact on people’s lives. We are crea­tive. We shape tech­no­logy. We design pro­ducts. We improve methods and tech­ni­ques. We open up new vis­tas.
