Themen für Masterarbeiten

Auf dem Gebiet der Raster­­tunnel­­mikro­skopie bei tiefen Temperaturen sind am Lehrstuhl EP2 mehrere Master­ar­bei­ten zu ver­ge­ben.  Eine hoch­wertige und mo­der­ne experi­­men­­telle Aus­­stat­tung ist vor­han­den!  Bei der Durchführung der Projekte werden Sie mit einem klei­nen Team zusammenarbeiten.  Hier eine kurze Themenliste:

  • Skyrmionen in antiferromagnetischen Filmen (DFG ge­för­dert im Rahmen des SPP "Skyrmionics")
  • STM-Untersuchungen des Wachstums und der elektronische Eigenschaften epitaktischer SnTe- und PbSnTe-Filme (im Rahmen des SFB 1170 "ToCoTronics"; Teilprojekt A02; Publikation)
  • Magnetische Ordnungsphänomene eindimensionaler Übergangsmetalloxid-Strukturen auf Pt(001) (DFG ge­för­dert durch FOR 1700, Teilprojekt E6)
  • Studien zum elektronischen Transport in Oberflächen mittels Molecular Nanoprobe (MONA)

Bei Inter­es­se melden Sie sich bitte bei Prof. Matthias Bode (Stand 08.10.2018).

A switchabe molecular magnet

The control of the charge- and spin state of single molecules is key for the design of mo­le­cu­lar elec­tro­nic and spin­tro­nic de­vi­ces.  For swit­ching the spin or mag­ne­tic state of mo­le­cules two prin­ci­ples have been used in the past:  (1) atoms or small mo­le­cu­les were ad­ded to and re­mo­ved from the host mo­le­cule or (2) by mo­di­fying the shape of mo­le­cu­les which can exist in more than one con­fi­gu­ra­tion.  The re­a­li­za­tion of both me­thods is ra­ther dif­fi­cult.  In co­ope­ration with theo­rists around Prof. Giorgio Sangiovanni (TP I), in a re­cent pub­li­ca­tion our group presented an al­ter­na­tive way to achieve mul­tiple and re­ver­si­bly switchable spin states in a single mo­le­cu­les.   These re­sults show that a bi­stable mo­le­cu­lar state can be achie­ved by po­si­tio­ning single man­ga­nese phthalo­cyanine (MnPc) mo­le­cu­le on top of an anti­phase boun­da­ry of the (3×3)-recon­struc­ted sur­face alloy of bismuth on Ag(111).   In this environment we can switch single molecules bet­ween a high- and a low-spin state by using the elec­tric field of a sharp STM tip.  The result has been pub­lished in npj Quantum Materials


New group member: Robert Schindhelm

In October Robert Schindhelm began his master thesis towards MONA experiments on strongly spin-orbit-coupled surfaces.  He will join the team around the LT-2 and CryoMag setup.  Welcome!


New group member: Paula Weber

In October Paula Weber joined our the LT-3 team to begin her PhD project.  She will perform spin-polarized scanning tunneling microscopy studies of thin transition metal films to explore complex spin structures, such as spin spirals or Skyrmions.  Welcome!
