Stellenticket Technische Hochschule Wildau

Pos­i­tion: RTG2767-A6
Invest­ig­at­ors: Dr. Bernd Rel­ling­haus / Prof. Dr. Andreas Fery
Terms: 75 % of the full-time weekly hours
Tasks: In situ and in oper­ando char­ac­ter­iz­a­tion of func­tional self-assembled
nano­struc­tures
Require­ments: excel­lent uni­versity degree (Mas­ter of Sci­ence or dip­loma) in phys­ics, mater­i­als sci­ence, or chem­istry; Exper­i­ence in exper­i­mental trans­mis­sion elec­tron micro­scopy. Addi­tional exper­i­ences in the pro­cessing of nano­struc­tured or nan­o­par­tic­u­late mater­i­als are appre­ci­ated.

Descrip­tion of the PhD task
The pro­ject aims at under­stand­ing and con­trolling self-assembly pro­cesses dur­ing both the growth and assembly of nano­scopic func­tional ele­ments by using in-situ trans­mis­sion elec­tron micro­scopy (TEM). Here, the DNA-medi­ated assembly of nan­o­ma­ter­i­als and novel nano-actu­at­ors based on Au nanor­ods attached to DNA ori­ga­mis shall be dir­ectly observed by liquid phase elec­tron micro­scopy in order to identify and optim­ize kin­etic para­met­ers that gov­ern the assembly pro­cesses. Also, the elec­tric­ally biased switch­ing of nano-actu­at­ors is planned to be mon­itored oper­ando in the micro­scope. Since col­lat­eral beam dam­age is unavoid­able in in-situ TEM, low dose strategies need to be developed and ex-situ con­trol exper­i­ments using ana­lyt­ical high-res­ol­u­tion TEM are to be con­duc­ted to quantify and min­im­ize such beam-induced arte­facts.

About the RTG
The RTG 2767 aims to train a new gen­er­a­tion of experts who will design mater­i­als made of supra­col­loidal struc­tures from the draw­ing board to applic­a­tion in com­pon­ents. Nan­o­particles are used in many optical and elec­tronic com­pon­ents nowadays. Supra­col­loidal struc­tures are com­plex super­struc­tures com­posed of dif­fer­ent nan­o­particles, sim­ilar to how atoms are linked to molecules. This res­ults in innov­at­ive, excep­tion­ally prom­ising optical and elec­tronic prop­er­ties that go far bey­ond those of the indi­vidual build­ing blocks. To date, these struc­ture-prop­erty rela­tion­ships of the assembled particles are not adequately under­stood. The tech­no­lo­gical vis­ions of these new mater­i­als include novel solar cells, field amp­li­fic­a­tion for highly sens­it­ive spec­tro­scopy, bio­sensing applic­a­tions where com­plex detec­tion pro­cesses are made sim­pler, and even on-site sample exam­in­a­tion using smart­phones. In order to real­ize the tech­nical com­plex­ity in the train­ing, numer­ous insti­tu­tions are con­nec­ted within the RTG’s 2767 tight net­work, includ­ing vari­ous groups at the TU Dresden, the Uni­versität Leipzig, the TU Dresden Research Cluster cfaed and the Dresden Cen­ter for Nanoana­lysis as well as the Leib­niz-Insti­tut für Poly­mer­forschung Dresden e. V., the Helm­holtz-Zen­trum Dresden - Rossen­dorf e. V. and the Kurt-Schwabe-Insti­tut für Mess- und Sensor­tech­nik Meins­berg e.V.

You will join an enthu­si­astic and ambi­tious research train­ing group, where you can drive your pro­ject for­ward and bene­fit from inspir­a­tional inter­ac­tions with like-minded research­ers. The RTG offers struc­tured train­ing pro­gram with tech­nical and soft skill courses, research stays abroad as well as con­tact to industry. It offers the oppor­tun­ity for PhD thesis com­ple­tion. The work­ing lan­guage of our inter­na­tional teams is Eng­lish.
