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

The Leib­niz-Insti­tute for Crys­tal Growth (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 ur-gent 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 interna-tional part­ners from uni­versity, academy and industry. The insti­tute is part of Forschungs­ver­bund Ber-lin ( and a mem­ber of the Leib­niz Asso­ci­ation You can find more details on the insti­tute webpage:

“Multi-phys­ics sim­u­la­tion for crys­tal growth”

Work­ing field:

Within the frame­work of a highly regarded Start­ing Grant from the European Research Coun­cil (ERC) we are set­ting up a group "Model exper­i­ments" at the IKZ to work on a new gen­er­a­tion of mul­tiphys­ical mod­els for crys­tal growth pro­cesses (see News on our webpage). The pro­ject team will develop a ded­ic­ated exper­i­mental plat­form to study heat trans­fer, elec­tro­mag­net­ism, melt and gas flows as well as crys­tal stresses in order to build and val­id­ate coupled numer­ical mod­els. Here you will gain unique exper­i­ence while work­ing in an inter­dis­cip­lin­ary team on ground-break­ing sci­ence.
Your tasks:
  • Ana­lyze selec­ted crys­tal growth pro­cesses at IKZ (e.g., float­ing zone growth of sil­icon) with respect to heat trans­fer and elec­tro­mag­netic aspects in par­tic­u­lar
  • Identify phys­ical mod­els and their para­met­ers for the descrip­tion of all rel­ev­ant phe­nom­ena
  • Develop val­id­a­tion strategies using ded­ic­ated model exper­i­ments based on sim­il­ar­ity cri­teria, per­form the neces­sary tri­als and meas­ure­ments
  • Imple­ment the mod­els in open source soft­ware lib­rar­ies (e.g., Elmer, Open­FOAM)
  • Describe und pub­lish model demon­strat­ors, applic­a­tions, and bench­mark cases


  • MSc or equi­val­ent degree in phys­ical sci­ences or related dis­cip­line with an excel­lent score
  • Solid know­ledge in the devel­op­ment and val­id­a­tion of mod­els for com­plex phys­ical pro­cesses
  • Excel­lent cap­ab­il­ity of sci­entific work as well as its doc­u­ment­a­tion and present­a­tion
  • Prac­tical exper­i­ence in numer­ical sim­u­la­tion using finite ele­ments or sim­ilar meth­ods
  • Skills in pro­gram­ming and script­ing lan­guages (e.g., C++, Python)

What we of­fer:

The pos­i­tion is lim­ited to 3 years, an exten­sion for another year is pos­sible. Pay­ment is accord­ing to TVöD (75%) (Treaty for Ger­man pub­lic ser­vice). IKZ is an equal oppor­tun­ity employer. There­fore, female can­did­ates are encour­aged to apply and will be pre­ferred in case of adequate qual­i­fic­a­tion. Among equally qual­i­fied applic­ants pref­er­ence will be given to dis­abled can­did­ates. IKZ sup­ports the com­pat­ib­il­ity of job and fam­ily and is cer­ti­fied as fam­ily-friendly by the "Job and Fam­ily" audit.
