Do you want to work in the field of advanced materials and be involved in a high profile research project on the forefront of science? DTU Energy invites applications for a PhD scholarship within development of micro four-point probe (M4PP) based metrology methods for semiconductor characterization within thermoelectrics and nanoelectronics.<br /><br />M4PP measurements offer a unique opportunity to observe thermoelectric transport phenomena in semiconductors. We will use this opportunity to investigate length-dependent heat and charge transport.<br /><br /><strong>Application to thermoelectrics</strong><br />The efficiency of a thermoelectric material, to heat/cool or to convert heat into electricity, depends on thermoelectric material properties like the Seebeck coefficient, electrical resistivity and thermal conductivity. Within this project, we will demonstrate that these three key material properties can be measured simultaneously in just 10 seconds with an M4PP.<br /><br /><strong>Application to nanoelectronics</strong><br />With thermoelectric measurements, we can also evaluate material properties in one-dimensional source/drain contacts, which is of key importance for optimizing semiconductor device performance. With an M4PP we can measure the line resistance of such one-dimensional structures, and within this project we will further develop methods to extract carrier concentration, mobility and temperature coefficient of resistivity.<br /><br /><strong>Responsibilities and tasks </strong><br />You will be part of the national research project “Metrology for Energy and Electronic Materials” supported by the Danish Council for Independent Research. Measurements are performed on fully automated M4PP systems, and you will take part in developing these new metrology methods to extract material properties with high precision, accuracy and spatial resolution.<br /><br />You will work in collaboration with our team to develop data acquisition strategies, structuring measurement data and extracting material properties in order to achieve high measurement precision (reproducibility/repeatability). You will be responsible for removing systematic measurement artifacts, by implementing correction algorithms to our data treatment scripts (Matlab). And finally, you will search for systematic signatures of nanoscale thermoelectric transport phenomena.<br /><br /><strong>Qualifications</strong><br />You should have a two-year master's degree in engineering/physics (120 ECTS points) or a similar degree with an academic level equivalent to a two-year master's degree.<br /><br />We strive towards performing exceptionally precise and accurate measurements. For this PhD position, we seek an independent experimentalist with a systematic approach in solving problems. You are a perfectionist who enjoys trouble shooting until the final digit is correct.<br /><br />Experience in one or more of the following will be an advantage:<br /> <ul><li>Matlab programming</li><li>Electrical measurement methods</li><li>Lock-in technique</li><li>Microfabrication</li><li>Thermoelectric effects</li><li>Semiconductor device physics</li><li>COMSOL Multiphysics or similar finite element method software</li></ul><br /><strong>Approval and Enrolment</strong><br />The scholarship for the PhD degree is subject to academic approval, and the candidate will be enrolled in one of the general degree programmes at DTU.
