Investigation of local breakdown of the Quantum Hall effect in graphene probed with invasive metal contacts:
No full textWe investigate the local breakdown of the Quantum Hall Effect (QHE) effect in a graphene device caused by the constraints of the Hall bar geometry and finite size of the sample. First to account for principal features of the data we use a multi-carrier model that simulates the transverse and longitudinal resistance of doped samples in low magnetic fields. This model however can not reproduce the reduction of Hall voltage measured in the vicinity of the current leads. Therefore we introduce a second model which describes the effect of distribution of electric field in the device, giving a reasonable scenario that can explain our experimental data and deviations from the case of perfect geometry. We conclude that the existence of Hot Spots in two corners of the sample leads to the local break down of the QHE around this points.M.S.Includes bibliographical references (p. 65-68)by Fabian Duer

Editor\u27s Introduction
No full textThe author reflects on the issues presented at the Conflict Resolution Quarterly (CRQ) which includes the work of organizational ombudsman, court mediators, mediation trainers, and peace accords. She focuses on the role of mediators and their impact on future court regarding self-selection bias and mediation programs. She presents the details based on the researches by Landon Hancock, Joshua Weiss, and Glen Duerr in regards with mediation for conflict management and justice administration
