CERBERUS – Farebné centrá v diamante – korelácia medzi atómovou štruktúrou a optoelektronickými vlastnosťami
Colour centres in diamond – correlation between atomic structure and opto-electronic properties
Program: SRDA
Project leader: Ing. Varga Marian, PhD.
Annotation: The subject of the project is in the field of quantum technologies. We will prepare and characterize optically -activedefects in diamonds and correlate the atomic structures with optical properties to be used for quantum applicati ons.For a wide range of dopant concentrations, we will identify the dopant distributions and study the evolution ofdopants’ configuration in-situ, during thermal annealing, using atomic-resolution microscopy and spectroscopytechniques. We will further study the effect of annealing on the opto-electronic properties by measuringphotoluminescence, photocurrent and electroluminescence for the same set of samples. Graphene transparentelectrodes on a diamond surface will be fabricated for phototransport measurements. Diamond-based hybrid p-i-ndiodes will be prepared for electroluminescence measurements. We will focus on finding a correlation between theatomic structure and the opto-electronic properties of differently doped diamonds. This will contribute to theunderstanding of the fundamental relationship needed to efficiently design optically -active elements for diamondquantum devices.
