Single-shot read-out of an individual electron spin in a quantum dot.

Nature

Elzerman JM, Hanson R, Willems Van Beveren LH, Witkamp B, Vandersypen LM, Kouwenhoven LP.
PMID: 15269762
Nature. 2004 Jul 22;430(6998):431-5. doi: 10.1038/nature02693.

Spin is a fundamental property of all elementary particles. Classically it can be viewed as a tiny magnetic moment, but a measurement of an electron spin along the direction of an external magnetic field can have only two outcomes:...

Strong coupling between single-electron tunneling and nanomechanical motion.

Science (New York, N.Y.)

Steele GA, Hüttel AK, Witkamp B, Poot M, Meerwaldt HB, Kouwenhoven LP, van der Zant HS.
PMID: 19628816
Science. 2009 Aug 28;325(5944):1103-7. doi: 10.1126/science.1176076. Epub 2009 Jul 23.

Nanoscale resonators that oscillate at high frequencies are useful in many measurement applications. We studied a high-quality mechanical resonator made from a suspended carbon nanotube driven into motion by applying a periodic radio frequency potential using a nearby antenna....

Time-resolved magnetization dynamics of cross-tie domain walls in permalloy microstructures.

PMID: 21836205
J Phys Condens Matter. 2009 Dec 02;21(49):496001. doi: 10.1088/0953-8984/21/49/496001. Epub 2009 Nov 12.

We report on a picosecond time-resolved x-ray magnetic circular dichroic-photoelectron emission microscopy study of the evolution of the magnetization components of a microstructured permalloy platelet comprising three cross-tie domain walls. A laser-excited photoswitch has been used to apply a...

Zeeman energy and spin relaxation in a one-electron quantum dot.

Physical review letters

Hanson R, Witkamp B, Vandersypen LM, van Beveren LH, Elzerman JM, Kouwenhoven LP.
PMID: 14611599
Phys Rev Lett. 2003 Nov 07;91(19):196802. doi: 10.1103/PhysRevLett.91.196802. Epub 2003 Nov 07.

We have measured the relaxation time, T1, of the spin of a single electron confined in a semiconductor quantum dot (a proposed quantum bit). In a magnetic field, applied parallel to the two-dimensional electron gas in which the quantum...

Pumping of vibrational excitations in the coulomb-blockade regime in a suspended carbon nanotube.

Physical review letters

Hüttel AK, Witkamp B, Leijnse M, Wegewijs MR, van der Zant HS.
PMID: 19658876
Phys Rev Lett. 2009 Jun 05;102(22):225501. doi: 10.1103/PhysRevLett.102.225501. Epub 2009 Jun 02.

Low-temperature transport spectroscopy measurements on a suspended few-hole carbon nanotube quantum dot are presented, showing a gate-dependent harmonic excitation spectrum which, strikingly, occurs in the Coulomb-blockade regime. The quantized excitation energy corresponds to the scale expected for longitudinal vibrations...

Bending-mode vibration of a suspended nanotube resonator.

Nano letters

Witkamp B, Poot M, van der Zant HS.
PMID: 17163728
Nano Lett. 2006 Dec;6(12):2904-8. doi: 10.1021/nl062206p.

We have used a suspended carbon nanotube as a frequency mixer to detect its own mechanical motion. A single gate-dependent resonance is observed, which we attribute to the fundamental bending mode vibration of the suspended carbon nanotubes. A continuum...
