RWTH Aachen - Institut für Theoretische Elektrotechnik

Semiconductor devices are the basis of all electronic applications: from smartphones over photovoltaics and high-speed data transfer to power electronics for electromobility. Therefore, a fundamental physical understanding of these devices on a microscopic level is desirable in order to improve currently applied technologies as well as to figure out the capabilities of possible future devices.
At the Chair of Electromagnetic Theory, we conduct research on physical models for semiconductor devices, we develop numerical methods for that purpose and we perform microscopic simulations of such devices on our own computer cluster.
The teaching of our institute covers the lectures about electromagnetic fields for bachelor students and specialized courses in semiconductor device simulations for master students.

Research Assistant/Associate

Work­ing field:

  • You will work on deve­lo­ping a micro­scopic model to simu­late the ope­ra­tion of Redox-based ran­dom-access memo­ries (ReRAM). As an emer­ging non-vola­tile memory device, ReRAM is expec­ted to over­come the limi­ta­ti­ons of the semi­con­duc­tor-based NVMs such as sca­la­bi­lity and power con­sump­tion.
  • Opti­mi­za­tion of the per­for­mance of these devices with respect to relia­bi­lity, reten­tion time and sca­la­bi­lity is one of the main issues facing ReRAM. Under­stan­ding the ori­gin of these ope­ra­tio­nal chal­len­ges and its mecha­nisms is the main goal, which is nee­ded to be addres­sed in this work. Stu­dy­ing these effects requi­res a large num­ber of repeated simu­la­ti­ons, which demands a fast yet accu­rate method to simu­late the device ope­ra­tion. To this end you will use the KMC method to handle this with rea­son­able com­pu­ta­tio­nal power and CPU time.
  • You will join the third period of the pro­ject ‘col­la­bo­ra­tive rese­arch cen­ter 917 (SFB 917 Nanos­wit­ches)’, a large inter­di­sci­pli­nary rese­arch pro­ject invol­ving che­mi­stry, mate­rial sci­en­ces, phy­sics and elec­tri­cal engi­nee­ring. In the first period of this pro­ject a simu­la­tion frame­work was deve­lo­ped to model the resis­tive swit­ching in ReRAM. You will use this model as a base and improve the invol­ved phy­si­cal pro­ces­ses and the con­duc­tion mecha­nisms.


  • A uni­ver­sity degree (mas­ter or com­pa­ra­ble) in elec­tri­cal engi­nee­ring or phy­sics with above average results is man­datory.
  • Expe­ri­en­ces in elec­tro­nic devices, semi­con­duc­tor phy­sics, nume­ri­cal mathe­ma­tics and high-per­for­mance com­pu­ting are appre­cia­ted.
  • Since you will work in an inter­na­tio­nal team, the capa­city for team work as well as good Eng­lish skills, writ­ten and spo­ken, are requi­red.
