Leib­niz-Insti­tut für Kris­tall­züch­tung im For­schungs­ver­bund Ber­lin e.V. - -

The Leib­niz-Insti­tut für Kristallzüch­tung (IKZ) is a lead­ing research insti­tu­tion in the area of sci­ence & tech­no­logy as well as ser­vice & trans­fer of crys­tal­line mater­i­als. Our goal is to enable solu­tions for urgent soci­etal chal­lenges (e.g. com­mu­nic­a­tion, arti­fi­cial intel­li­gence, cli­mate pro­tec­tion, health etc.). by mod­ern elec­tronic & photonic tech­no­lo­gies. The work cov­ers the full spec­trum from basic over applied research up to pre-indus­trial devel­op­ment and is per­formed in col­lab­or­a­tion with national and inter­na­tional part­ners from uni­versity, academy and industry. The insti­tute is part of the Forschungs­ver­bund Ber­lin (https://www.fv-berlin.de/) and a mem­ber of the Leib­niz Asso­ci­ation www.leibniz-gemeinschaft.de. You can find more details on the insti­tute webpage: www.ikz-berlin.de.

“Mod­el­ing of the indus­trial Float­ing Zone Pro­cess for large ultrapure Sil­icon Single Crys­tals”

Work­ing field:

Ultrapure Sil­icon single crys­tals grown using the Float Zone method are cur­rently in high demand for trend­ing tech­no­lo­gies and excit­ing sci­entific applic­a­tions. The crys­tals are needed for elec­tronic devices (e.g. in the renew­able energy value chain and e-mobil­ity), the emer­ging field of quantum tech­no­logy as well as in grav­it­a­tional-wave detect­ors that strive to expand our know­ledge of the uni­verse.
As a mem­ber of our sim­u­la­tion team you will con­trib­ute to our applied research in Float Zone pro­cess devel­op­ment and optim­iz­a­tion. Your task is to fur­ther develop our numer­ical mod­els in the Soft­ware COM­SOL Mul­tiphys­ics, for future 3D and time-depend­ent FEM cal­cu­la­tions. The val­id­ated mod­els should be able to describe all the rel­ev­ant and inter­de­pend­ent phys­ical phe­nom­ena tak­ing place dur­ing growth: elec­tro­mag­net­ism, heat trans­port, inter­faces and free sur­faces, fluid flow and segreg­a­tion. Your work will give sig­ni­fic­ant input to our growth exper­i­ments, car­ried out in our mod­ern Float Zone Sil­icon lab using an 8 inch fur­nace of the latest gen­er­a­tion.

Require­ments:

  • MSc or equi­val­ent degree in phys­ical/chem­ical/engin­eer­ing sci­ences
  • pro­found mod­el­ling back­ground in at least one of the fields: elec­tro­mag­net­ism, heat trans­port, CFD, phase change.
  • proven exper­i­ence in numer­ical mod­el­ing using COM­SOL Mul­tiphys­ics
  • Pro­gram­ming (e.g. C++, Python, Mat­lab) and Solid­Works skills are an advant­age.
  • author sci­entific pub­lic­a­tions and present on con­fer­ences in Eng­lish lan­guage

What we of­fer:

  • Pos­sib­il­ity to con­trib­ute to excit­ing applied sci­ence and spe­cial­ize in a high-tech sec­tor
  • Fixed term con­tract for 3 years with pay­ment accord­ing to TVöD (75%)

For aca­demic ques­tions please con­tact: Dr. Nata­scha Dropka at natascha.dropka@ikz-berlin.de.

Among equally qual­i­fied applic­ants, pref­er­ence will be given to dis­abled can­did­ates. The IKZ is an equal oppor­tun­ity employer and act­ively sup­ports recon­cili­ation of work and fam­ily life. There is equal­ity for applic­ants of all genders. Qual­i­fied women are espe­cially encour­aged to apply.
