Banerjee, S. (author)This thesis has explored the possibility of using carbon nanotubes (CNT) as a novel material for through-silicon vias (TSV) in 3D-integrated circuits. With the steady downscaling trend of the semiconductor industry, a major limiting factor to the overall performance of the device is the delay from interconnects; a trend that is worsening over...master thesis 2014

Vollebregt, S. (author)Interconnects in integrated circuits (IC) are the major cause of power dissipation and delay. 3D integration has been proposed as a method to reduce these issues. For this 3D integration, fabrication of high aspect ratio reliable vertical interconnects (vias) are required. For this new materials, like carbon nanotubes (CNT), are being considered...doctoral thesis 2014

Meerwaldt, H.B. (author), Johnston, S.R. (author), Van der Zant, H.S.J. (author), Steele, G.A. (author)We report fast readout of the motion of a carbon nanotube mechanical resonator. A close-proximity high electron mobility transistor amplifier is used to increase the bandwidth of the measurement of nanotube displacements from the kHz to the MHz regime. Using an electrical detection scheme with the nanotube acting as a mixer, we detect the...journal article 2013

(author)The presence in space of micrometeoroids and orbital debris, particularly in the lower earth orbit, presents a continuous hazard to orbiting satellites, spacecrafts and the international space station. Space debris includes all non-functional, man-made objects and fragments. As the population of debris continues to grow, the probability of...conference paper 2013

Vollebregt, S. (author), Banerjee, S. (author), Beenakker, K. (author), Ishihara, R. (author)The thermal conductivity of as-grown vertical multi-walled carbon nanotubes (CNT) bundles fabricated at low temperature (500?°C) was measured using a vertical 3?-method. For this, CNT were selectively grown inside an oxide opening and sandwiched between two metal electrodes. The validity of the method was confirmed by both measurements as...journal article 2013

Meerwaldt, H.B. (author)A carbon nanotube (CNT) is a remarkable material and can be thought of as a single-atom thick cylinder of carbon atoms capped of with a semisphere. This is called a single-walled CNT and, depending on how the cylinder is rolled up, CNTs are either semiconducting or metallic. A CNT is made into a mechanical resonator by suspending it between two...doctoral thesis 2013

Hortensius, H.L. (author), Öztürk, A. (author), Zeng, P. (author), Driessen, E.F.C. (author), Klapwijk, T.M. (author)Antenna-coupled suspended single carbon nanotubes exposed to 108?GHz microwave radiation are shown to be selectively heated with respect to their metal contacts. This leads to an increase in the conductance as well as to the development of a power-dependent DC voltage. The increased conductance stems from the temperature dependence of tunneling...journal article 2012

Götz, G.T.J. (author)We experimentally investigate Quantum Dots, formed in Carbon Nanotubes. The first part of this thesis deals with charge sensing on such quantum dots. The charge sensor is a metallic Single-electron-transistor, sensitive to the charge of a single electron on the quantum dot. We use this technique for real-time charge readout and precise tuning of...doctoral thesis 2010

Vollebregt, S. (author)In integrated circuits the delay caused by interconnects, their power consumption, production and reliability are challenges to be solved. Using the third dimension for additional layers of transistor has been proposed as a solution to this problem by reducing the length of the interconnects. A problem in 3D integration is the creation of...master thesis 2009
