Phy­si­ka­lisch-Tech­ni­sche Bun­des­an­stalt - VACANCY No. 19-86-7

The Physikalisch-Tech­nis­che Bundes­an­stalt (PTB) is the National Met­ro­logy Insti­tute of the Fed­eral Repub­lic of Ger­many with sci­entific and tech­nical ser­vice tasks. It fur­thers pro­gress and reli­ab­il­ity in met­ro­logy for soci­ety, the eco­nomy and sci­ence.

The PTB in Ber­lin-Adler­shof uses syn­chro­tron radi­ation from the elec­tronen stor­age rings Met­ro­logy Light Source (MLS) and BESSY II for met­ro­logy at own beam­lines. The pro­gress­ing min­itur­iz­a­tion, espe­cially in semi­con­ductor fab­ric­a­tion, presents new chal­lenges for met­ro­logy. For the fur­ther devel­op­ment of appro­pri­ate meas­ur­ing tech­niques, Depart­ment 7.2 "X-ray meas­ure­ment tech­no­logy with syn­chro­tron radi­ation" of Divi­sion 7 is look­ing for a doc­toral can­did­ate, spe­cial­iz­ing in phys­ics, applied math­em­at­ics or a rel­ev­ant engin­eer­ing sci­ence to join us as soon as pos­sible. The pos­i­tion is avail­able on the basis of a 3-year fixed-term con­tract. The renu­mer­a­tion will be in accord­ance with renu­mer­a­tion group 13 TVöD Bund (85 %). You will be employed at our Ber­lin-Adler­shof site.

Doc­toral can­did­ate, spe­cial­iz­ing in phys­ics, applied math­em­at­ics or a rel­ev­ant engin­eer­ing sci­ence

Focus: Char­ac­ter­iz­a­tion of nan­o­ma­ter­i­als with the help of X-ray spec­tro­metry under graz­ing incid­ence or graz­ing detec­tion

Graz­ing incid­ence or graz­ing exit X-ray fluor­es­cence (GIXRF / GEXRF) is used at PTB to char­ac­ter­ize dif­fer­ent nano­struc­tures, from simple lay­ers to three-dimen­sional struc­tures. PTB's own meas­ure­ment setups enable dimen­sional char­ac­ter­iz­a­tion and trace­able quan­ti­fic­a­tion of the dif­fer­ent ele­ments present in a sample. These meas­ur­ing prin­ciples are to be fur­ther developed espe­cially for state-of-the-art applic­a­tions in the semi­con­ductor industry.

Work­ing field:

  • Inde­pend­ent con­cep­tion, exe­cu­tion and data eval­u­ation of X-ray spec­tro­met­ric exper­i­ments
  • Mod­el­ing and sim­u­la­tion of elec­tro­mag­netic fields using numer­ical meth­ods
  • Determ­in­a­tion of meas­ure­ment uncer­tain­ties by means of stochastic cal­cu­la­tions (for example Monte Carlo method)
  • Applic­a­tion and fur­ther devel­op­ment of meth­ods of machine learn­ing and uncer­tainty determ­in­a­tion


  • Ger­man Mas­ter's or "Dip­lom" with a degree in phys­ics or an adjoin­ing sub­ject with a strong interest in phys­ical exper­i­ments and mod­el­ing
  • Know­ledge and prac­tical exper­i­ence in at least one of the fol­low­ing desir­able fields: X-ray exper­i­mental research and related meth­ods (e.g. X-ray fluor­es­cence ana­lysis, X-ray reflec­to­metry or scat­ter­ing), finite ele­ment meth­ods
  • Pro­gram­ming skills (such as Python) and interest in devel­op­ing the­or­et­ical mod­els through pro­pri­et­ary soft­ware solu­tions
  • inde­pend­ent, struc­tured way of work­ing
  • strong team and com­mu­nic­a­tion skills
  • good com­mand of spoken and writ­ten Ger­man and Eng­lish
  • Will­ing­ness to travel within Ger­many and abroad

PTB pro­motes the pro­fes­sional equal­ity of women and men and is thus espe­cially inter­ested in applic­a­tions from women.
Within the scope of the offi­cial feas­ib­il­it­ies, PTB offers flex­ible part-time work schemes in order to sup­port in par­tic­u­lar the com­pat­ib­il­ity of fam­ily and pro­fes­sion.
Dis­abled per­sons will be given pri­or­ity, if they have the same occu­pa­tional aptitude.
