About this role
Lund University was founded in 1666 and is consistently ranked among the world's leading higher education institutions. It has approximately 47,000 students and more than 8,800 employees in Lund, Helsingborg, and Malmö. We are united in our pursuit to understand, explain, and improve our world and the conditions of humanity.
Lund University welcomes applicants from diverse backgrounds and experiences. Equality, equal opportunities, and diversity are fundamental principles for all aspects of our operations.
**Description of the Workplace**
The doctoral position is affiliated with the Department of Solid State Physics at the Faculty of Science, which comprises around 100 employees and conducts extensive research centered on various aspects of nanophysics, ranging from materials science to bio- and quantum physics with various applications.
The department is a central part of NanoLund, Lund University's major interdisciplinary research center focused on nanoscience and nanotechnology.
A significant portion of the research at the department is directed towards the characterization of semiconductor materials. The department hosts Prof. Vanya Darakchieva's research group. Together with her collaborators, the group has developed ellipsometry with THz radiation and its applications in the characterization of semiconductor materials and components in recent years. The optical Hall effect is one of the advanced characterizations used to access electronic transport properties. This method has been applied to two-dimensional semiconductor systems such as nitride-based high electron mobility transistors and graphene, as well as to semiconductors with large bandgaps and low symmetry, such as Ga2O3. These materials and components lay the foundation for the next generation of high-frequency and high-power electronics being developed in collaboration with leading Swedish industry partners.

**Being a Doctoral Student**
As a doctoral student, you are both admitted as a student and employed by Lund University.
As a research student, you are trained in a scientific approach. This can be briefly described as gaining practice in critical and analytical thinking, solving problems independently using appropriate methods, and developing an awareness of research ethics. Additionally, you will have the opportunity to work on projects, develop your leadership skills, and enhance your pedagogical abilities. Throughout your studies, you will be guided by supervisors. Doctoral studies conclude with a dissertation and a doctoral degree.

**Subject and Project Description**
The supervisor for the doctoral project is Prof. Vanya Darakchieva at the Department of Solid State Physics. Vanya Darakchieva has extensive experience in developing new semiconductor materials for high-frequency and power electronics. The research also focuses on developing spectroscopic techniques to study electronic properties and transport characteristics of materials from bulk to nanoscale.
A specific direction to be further developed is to investigate electron spin resonances with the THz ellipsometer, known as high-field EPR. This involves the development of equipment and strategies based on polarization optical methods aimed at defect characterization in semiconductors. The development primarily concerns fundamental research but has strong connections to future concepts for quantum technology.
**Responsibilities**
You will primarily focus on your doctoral education, which includes participation in research projects as well as doctoral courses, seminars, and conferences.
The aim of this doctoral project is to conduct research in THz material analysis to expand the application of THz ellipsometry and the optical Hall effect to electron spin resonance ellipsometry. The method will primarily be applied within materials science, particularly for the investigation of crystal phases and defects in semiconductors. In addition to nitride material systems, a focus area will be Ga2O3 and other materials with ultra-wide bandgaps.
Your responsibilities will also include participation in teaching and other departmental work (up to a maximum of 20% of working time).
