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 to enable solu­tions in soci­ety by mod­ern tech­no­lo­gies (e.g. arti­fi­cial intel­li­gence, cli­mate pro­tec­tion, health etc.). Our work cov­ers the full spec­trum from basic over applied research up to pre-indus­trial devel­op­ment, includ­ing national and inter­na­tional part­ners from uni­versity, insti­tutes as well as industry. The insti­tute is part of For-schungs­ver­bund Ber­lin ( and a mem­ber of the Leib­niz Asso­ci­ation ( You can find more details at the insti­tute webpage:

PhD stu­dent for Mod­el­ing of Mul­tiphys­ical Pro­cesses (m/f/d)

Work­ing field:

Mod­ern crys­tal­line mater­i­als, that are the basis of innov­a­tions in micro­elec­tron­ics or renew­able energy, are pro­duced in com­plex high-tem­per­at­ure pro­cesses involving a large vari­ety of phys­ical phe­nom­ena. In the NEMO­CRYS pro­ject (see group "Model exper­i­ments" on our homepage), fun­ded by the European Union through the research & innov­a­tion pro­gram Hori­zon 2020, we are work­ing on a new gen­er­a­tion of mul­tiphys­ical mod­els for such pro­cesses. An innov­at­ive exper­i­mental plat­form using model mater­i­als provides com­pre­hens­ive data for the devel­op­ment and val­id­a­tion of new phys­ical mod­els, which is one of the major chal­lenges in crys­tal growth tech­no­logy. In our pro­ject you will gain unique exper­i­ence while work­ing in an inter­dis­cip­lin­ary team on ground-break­ing sci­ence shap­ing the pro­duc­tion of the mater­i­als of tomor­row.

Your tasks:
  • Ana­lyze mul­tiphys­ical phe­nom­ena (thermo-, elec­tro- and fluid dynam­ical aspects) of select-ed crys­tal growth pro­cesses at IKZ (e.g., float­ing zone growth of sil­icon)
  • Identify the essen­tial phys­ical mod­els for the descrip­tion of rel­ev­ant phe­nom­ena
  • Imple­ment your mod­els in open source soft­ware lib­rar­ies (e.g., Open­FOAM, Elmer)
  • Develop val­id­a­tion strategies using ded­ic­ated model exper­i­ments based on sim­il­ar­ity cri­teria, per­form the neces­sary tri­als and meas­ure­ments
  • Pub­lish your res­ults and thus help to develop the next gen­er­a­tion of crys­tal growth mod­els


  • 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 pro-cesses
  • 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.
