Electrical Properties of Grain Boundaries
The electrical properties of grain boundaries are very different in insulators, semiconductors and metals. We present them briefly in the case of insulators and semiconductors and with more details in the case of metals.
متن کاملElectronic properties of grain boundaries in semiconductors
2014 The aim of this communication is to describe the main results which we have obtained in the past years on the electronic properties of grain boundaries in semiconductors. The study, experimental as well as theoretical, has focused on the main electronic characteristics i.e. density of states, optical cross sections, carrier capture cross sections (and recombination velocity) from which all...
متن کاملThermoelectric Properties of Functionalized Graphene Grain Boundaries
Thermoelectric effect enables direct conversion between thermal and electrical energy and provides an alternative route for power generation and refrigeration. Hereby it is important to find materials with a high thermoelectric performance. In this sense, in the present work, we study the behavior of the thermoelectric properties of functionalized graphene grain boundaries by employing non-equi...
متن کاملElectrical Properties of Different Types of Grain Boundaries in Multicrystalline Silicon by Photoluminescence Imaging
There are numerous types of Grain Boundaries (GBs) present in multicrystalline silicon wafers, such as ∑3, ∑9, ∑27 and Random Angle (RA) GBs. Small-Angle Grain Boundaries (SA GBs) are also common, and often occur in locally dense networks, creating regions of high recombination. These GBs can limit the efficiency of multicrystalline silicon solar cells, especially when they are decorated with i...
متن کاملImpurity-induced microstructure of grain boundaries in cast silicon. Incidence on electrical properties
2014 The role of impurities in polysilicon for photocell has been investigated. Aluminium and carbon residual impurities in the Bridgman and HEM materials were particularly considered. The combination of local electrical, chemical and structural information with high spatial resolution, specifically in transmission electron microscopy, allowed to correlate the crystallography and chemistry with...
