Angular resolved photo emission energy spectroscopy Sb2Te3

Direct observation of Dirac fermions at the surface of topological insulators

Topological insulators (Tis), such as Bi2Te3 and Sb2Te3, are materials with insulating properties in bulk and topologically protected surface states with a linear energy dispersion. Because of the linear energy dispersion, carriers at the surface of Tis may be deemed as quasi-relativistic particles with fascinating properties, such as dissipationless and spin-locked charge transport. Therefore, Tis have the potential for future applications in the field of electronics / spintronics. More: Direct observation of Dirac fermions at the surface of topological insulators …

Atomic Layer Deposition

Start of operation on the nanocluster ALD

The atomic layer deposition (ALD) tool of the nanocluster, an Oxford ® FlexAL® ALD, is brought into service by researchers of the Peter Grünberg Institute. Insulating layers of oxides and nitrides can be deposited in the ALD. For the oxides, thermal deposition as well as deposition using oxygen plasma and ozone are available.

Spin Injection into InN a  Nanowire

Spin injection in semiconductor nanowires for future spin based computing

Jülich, September, 2012: In contrast to conventional electronics, where the electric charge is used for switching purpose, in spin electronics the magnetic property of the electron, its spin, is employed. It is expected that spin-based transistors outclass conventional transistors regarding speed and power consumption. More: Spin injection in semiconductor nanowires for future spin based computing …
