Mn-doping into CdS quantum dots (QDs) has been demonstrated a useful way to enhance the power conversion efficiency (PCE) of quantum dot sensitized solar cells (QDSCs), the detailed systematic study is needed to get a better fundamental understanding. This work focuses on the study of the effects of Mn dopant on light harvesting, charge transfer, and charge collection of the solar cells. The resul
Avdelningen för matematisk fysik är gemensam för naturvetenskaplig och tekniska (LTH) fakulteterna och är en del av fysiska institutionen. Forskningen bedrivs främst inom området kvantmekanisk mångpartikelfysik, vilket innefattar teoretisk kärnstrukturfysik, nanometerfysik, tidsberoende och icke-jämviktsfenomen, kvantinformation, atom-teori och materialmodellering, med flera samarbeten både intern
In this work, we investigate carrier recombination dynamics and defect-related emission behavior in high-indium content InGaN platelets containing a single quantum well (QW) and a transition layer (TL) using temperature-dependent monochromatic cathodoluminescence (CL) imaging and time-resolved CL (TRCL). At low temperature, monochromatic CL imaging reveals expanded apparent emitting area of both l
Converting information into work has, during the past decade, gained renewed interest as it gives insight into the relation between information theory and thermodynamics. Here, we theoretically investigate an implementation of Maxwell's demon in a double quantum dot and demonstrate how heat can be converted into work using only information. This is accomplished by continuously monitoring the charg
A fundamental postulate of quantum mechanics is that the Hamiltonian of a closed system is Hermitian, guaranteeing real-valued energies and conserved probabilities throughout the evolution of the system. However, for quantum systems where there is dissipation and crosstalk with the environment, such as a system of quantum dots connected to an environment of metallic leads, the dynamics of the syst
Using Burt's envelope function theory and the scattering matrix method, we investigate the hybridized electron-hole Landau levels in strained InAs/GaSb quantum wells sandwiched between wide-gap AlSb barrier layers under electric and a quantizing magnetic fields applied perpendicular to interfaces. At zero magnetic field, in the structures studied here, the lowest electron level in the InAs layer l
Independence and collaboration both play crucial roles in PhD students’ research practice and in their socialization into the PhD role. This study examines how theexpectation of PhD students' academic independence intersects with the need for more collaborative engagements within research groups. Drawing on interviews with supervisors and an analysis of co-authorship patterns in PhD studentdissert
