Konferensbidrag (övrigt vetenskapligt/konstnärligt)abstract
- We have performed a theoretical analysis of the operational characteristics of a carbon-nanotube-based three-terminal nanorelay. In the present study we focus on introducing short range forces into the model. We show is that these forces have a significant impact on the characteristics of the relay. We also investigate the nanorelay as a memory element, and conclude that this is a promising application.

Tidskriftsartikel (refereegranskat)abstract
- We have performed a theoretical analysis of the operational characteristics of a carbonnanotube-based three-terminal nanorelay. We show that short range and van der Waals forces have a significant impact on the characteristics of the relay and introduce design constraints. We also investigate the effects of dissipation due to phonon excitation in the drain contact, which changes the switching time scales of the system, decreasing the longest time scale by 2 orders of magnitude. We show that the nanorelay can be used as a memory element and investigate the dynamics and properties of such a device.

ELECTROMECHANICAL NANOTUBE TUNNELING DEVICE COMPRISING SOURCE, DRAIN AND GATE
- 2011
-
Patent (övrigt vetenskapligt/konstnärligt)abstract
- The present invention relates to a nanotube device (100) comprising a nanotube with a longitudinal and a lateral extension, a structure for supporting at least a first part of the nanotube, and first means for exerting a force upon the nanotube in a first direction defined by its lateral extension. At least a second part of the nanotube protrudes beyond the support of said structure, so that when said force exceeds a certain level, the second part of the nanotube will flex in the direction of its lateral extension, and thereby close a first electrical circuit. Suitably, the first means for exerting said force upon the nanotube is an electrical means, the force being created by applying a voltage to the means. The device allows for quantum mechanics tunnel effects, both at a source and at a drain electrode.

Tidskriftsartikel (refereegranskat)abstract
- At a time when more and more natural science subjects are attracting an increasing number of women (chemistry for example) physics remains a male stronghold. It is not easy to understand this phenomenon or the anomaly that over-representation of males in physics faculties is more likely to occur in countries known for their attempts at equalizing opportunities for women, Sweden, for example, has a parliament in which 40% of its members are women and yet the average percentage of women lecturers in physics faculties is about half of that. In Sweden today women professors of physics (both appointed and promoted) typically represent 10% or less of the total professorial staff. In this paper we report on a qualitative case study of gender equity in a large physics faculty in a Swedish university. In order to locate our study in a more general social and political context we look at Swedish legislation that seeks to equalize opportunities for women in higher education. The rest of the study focuses on a brief review of research in the area of gender issues in higher education and an analysis of interviews with three women in physics: one a professor, one a lecturer and the third a PhD student. The analysis discusses why the current disproportion exists, if it is a good or bad thing for physics and physicists and how one might rectify any perceived problems in terms or gender relations and gender equity.
