Tech­ni­sche Uni­ver­si­tät Dres­den - Cen­ter for Advan­cing Elec­tro­nics Dres­den, Dres­den Cen­ter for Nano­ana­ly­sis (DCN)

The TU Dresden is one of eleven Ger­man uni­versit­ies that were iden­ti­fied as an “excel­lence uni­versity”. TUD has about 36.500 stu­dents and almost 5319 employ­ees, 507 pro­fess­ors among them, and, thus, is the largest uni­versity in Sax­ony, today.

Hav­ing been com­mit­ted to sci­ences and the engin­eer­ing before the reuni­fic­a­tion of Ger­many, TU Dresden now is a multi-dis­cip­line uni­versity, also offer­ing human­it­ies and social sci­ences as well as medi­cine.

The Cen­ter for Advan­cing Elec­tron­ics Dresden offers in its ana­lyt­ical cen­ter Dresden Cen­ter for Nanoana­lysis (DCN), sub­ject to resources being avail­able, a pos­i­tion as
Research Asso­ci­ate / PhD Stu­dent (m/f/x)
(sub­ject to per­sonal qual­i­fic­a­tions, employ­ees are remu­ner­ated accord­ing to salary group E 13 TV-L)
start­ing Octo­ber 1, 2022, lim­ited for 3 years, with the option for exten­sion. The period of employ­ment is gov­erned by the Fixed Term Research Con­tracts Act (Wis­senschaft­szeitver­trags­ge­setz - Wis­sZeitVG). The pos­i­tion aims at obtain­ing fur­ther aca­demic qual­i­fic­a­tion (e.g. PhD).

Invest­ig­at­ors: Dr. Darius Pohl
Terms: 75 % of the full-time weekly hours
Tasks: Atom­ic­ally resolved EMCD on fer­ri­mag­nets meas­ured with elec­tron vor­tex beams
Require­ments: excel­lent uni­versity degree (Mas­ter of Sci­ence or dip­loma) in phys­ics, mater­i­als sci­ence, or chem­istry; exper­i­ence in exper­i­mental trans­mis­sion elec­tron micro­scopy. Addi­tional exper­i­ences with mag­netic mater­i­als, elec­tron energy loss spec­tro­scopy (EELS) or elec­tron energy loss mag­netic chiral dichro­ism (EMCD) are appre­ci­ated.

Working field:

Posi­tion and tasks: Elec­tron vor­tex beams carry a dis­crete orbi­tal angu­lar momen­tum, and are pre­dic­ted to reveal elec­tron energy loss magne­tic chi­ral dich­ro­ism (EMCD) upon inter­ac­ting with magne­tic sam­ples down to the ato­mic scale. Howe­ver, proof-of-con­cept expe­ri­ments so far fai­led since the weak magne­tic signal is still hid­den behind the poor signal-to-noise ratio (SNR) of the acqui­red spec­tra. Wit­hin this pro­ject we the­re­fore seek to deve­lop stra­te­gies to improve the SNR on the metho­di­cal side as well as on the mate­ri­als side – both of which are essen­tial for a suc­cess­ful proof-of-con­cept expe­ri­ment. We anti­ci­pate to build a fun­da­men­tal under­stan­ding of how elec­tron vor­tex beams with high spa­tial cohe­rence and purity can be gene­ra­ted and how dif­fe­rent mate­rial pro­per­ties impact on the SNR for the detec­tion of an ato­mi­c­ally resol­ved EMCD signal.
Working on aberra­tion cor­rec­ted TEM with a newly deve­lo­ped path of rays for vor­tex micro­scopy, impro­ve­ment of vor­tex aper­ture qua­lity, data ana­ly­sis, and magne­tic mate­rial pre-cha­rac­te­ri­za­tion. In addi­tion, the pro­ject is stron­gly sup­port by inelastic scat­te­ring simu­la­ti­ons, which help to under­stand the com­plex inter­ac­tion mecha­nisms.

Requirements:

Gene­ral Requi­re­ments:
  • above-average uni­ver­sity degree achie­ved in short study period,
  • wil­ling­ness and abi­lity to think bey­ond the bounda­ries of your field, to act in an inter­na­tio­nal and diverse envi­ron­ment and to live an open and con­struc­tive com­mu­ni­ca­tion,
  • strong ana­ly­tic and pro­blem-sol­ving skills, crea­ti­vity,
  • an inde­pen­dent, tar­get- and solu­tion-dri­ven work atti­tude,
  • flu­ency in Eng­lish, know­ledge of Ger­man would be a plus.

What we offer:

You will join an enthu­si­astic and ambi­tious rese­arch group, where your work will inspi­red by the inter­ac­tions with open-min­ded fel­low sci­en­tists in a highly diverse rese­arch land­s­cape.

About the DCN
The Dres­den Cen­ter for Nano­ana­ly­sis (DCN) was foun­ded in Novem­ber 2012 as tech­no­logy plat­form of the 'Cen­ter for Advan­cing Elec­tro­nics Dres­den'. Embed­ded in the DRES­DEN-con­cept rese­arch alli­ance, it ser­ves as a com­pe­tence cen­ter of TU Dres­den. Rese­arch at the DCN has a strong focus on the struc­tu­ral and che­mi­cal ana­ly­sis of nanos­cale mate­ri­als using elec­trons and x-rays with an empha­sis on novel in-situ and in-ope­rando tech­ni­ques. The cen­ter pro­vi­des a highly inter­di­sci­pli­nary working envi­ron­ment in a newly con­struc­ted state-of-the-art lab infra­st­ruc­ture inclu­ding two ultra-low noise labo­ra­to­ries for ana­ly­ti­cal high-reso­lu­tion trans­mis­sion elec­tron micro­scopy. Besi­des pur­suing own rese­arch inte­rest, the DCN offers its infra­st­ruc­ture and know-how as ser­vice to the TU Dres­den as a whole. https://cfaed.tu-dresden.de/dcn
