Paul-Drude-Institut für Festkörperelektronik Leibniz-Institut im Forschungsverbund Berlin e. V.

The Paul Drude Insti­tute (PDI) per­forms basic research as a lively sym­bi­osis of mater­i­als sci­ence and solid state phys­ics. Our research aims at inspir­ing and demon­strat­ing new func­tion­al­it­ies for future inform­a­tion tech­no­lo­gies. As a mem­ber of the Leib­niz-Gemeinsch­aft and Forschungs­ver­bund Ber­lin e. V., we are an inde­pend­ent research insti­tute with about 100 employ­ees and col­lab­or­ate with all three uni­versit­ies in Ber­lin. We are loc­ated in the very heart of the city near Gen­dar­men­markt. You may find more details at

Ph.D. Pos­i­tion

for Cath­odo­lu­min­es­cence Spec­tro­scopy of Core/Shell Nanowires

Work­ing field:

The Paul-Drude-Insti­tute has a long-stand­ing expert­ise in cath­odo­lu­mines-cence spec­tro­scopy (CL) of group III-V semi­con­ductor nano­struc­tures car­ried out in a scan­ning elec­tron micro­scope (SEM). These meas­ure­ments of the emis­sion prop­er­ties can be dir­ectly cor­rel­ated to meas­ure­ments of the crys­tal struc­ture by elec­tron backs­cat­ter dif­frac­tion (EBSD) and of the prop­er­ties of a p-n junc­tion by elec­tron beam induced cur­rent (EBIC), both in the same SEM. Within a pro­ject fun­ded by the Bundesmin­is­terium für Bildung und Forschung (BMBF), we are cur­rently devel­op­ing nano-lasers based on GaAs/(In,Ga)As core/shell nanowire struc­tures for the dir­ect integ­ra­tion on Si wave­guides. In this con­text, it is import­ant to achieve a detailed under­stand­ing of their emis­sion prop­er­ties and of the influ­ence of the choice of com­pos­i­tion, dimen­sions, dop­ing, and crys­tal struc­ture on their optical prop­er­ties. In addi­tion, the per­form­ance of fully pro­cessed nano-lasers will also be invest­ig­ated. The Ph.D. can­did­ate is expec­ted to carry out CL, EBSD, and EBIC meas­ure­ments on GaAs/(In,Ga)As core/shell nanowires.


We invite applic­a­tions from exper­i­mental solid state phys­i­cists with a com­pet­it­ive mas­ter degree in phys­ics. Exper­i­ence with scan­ning elec­tron micro­scopy, lumin­es­cence spec­tro­scopy and/or work­ing with semi­con­ductor nanowires is advant­age­ous. We are look­ing for a col­league who enjoys work­ing in a highly motiv­ated team of research and tech­nical staff.

What we of­fer:

The pos­i­tion is avail­able for up to 3 years start­ing June 1st, 2019. Pay­ment is accord­ing to TVöD (Treaty for Ger­man pub­lic ser­vice). The Paul Drude Insti­tute aims at increas­ing the quota of female employ­ees. The applic­a­tion of women is there­fore encour­aged. Among equally qual­i­fied applic­ants, pref­er­ence will be given to dis­abled can­did­ates.

How to ap­ply:

Applic­a­tions should be sent by May 15th, 2019, with the ref­er­ence PhD-CL to:
