The Stability

The development of quasi-two-dimensional (2D) Ruddlesden-Popper phase perovskite solar cells (PSCs) has greatly improved the stability of devices. However, the presence of quantum confinement effects and insulating spacer cations in...

Theoretical Results

ABSTRACTIn this paper we studied the thermoelectric power under classically large magnetic field (TPM) in quantum wells (QWs), quantum well wires (QWWS) and quantum dots (QDs) of Bi by formulating the respective electron dispersion laws. The TPM increases with increasing film thickness in an oscillatory manner in all the cases. The TPM in QD is greatest and the least for quantum wells respectively. The theoretical results are in agreement with the experimental observations as reported elsewhere.
