Title: | Nitrogen-vacancy nanodiamond based local thermometry using frequency-jump modulation | Authors: | Singam, SKR NESLADEK, Milos GOOVAERTS, Etienne |
Issue Date: | 2020 | Publisher: | IOP PUBLISHING LTD | Source: | Nanotechnology, 31 (10) (Art N° 105501) | Abstract: | A straightforward and sensitive approach is presented for contact-free thermal sensing with high spatial resolution based on optically detected magnetic resonance (ODMR) of negatively charged nitrogen-vacancy (NV) centers in fluorescent nanodiamonds. The frequency-jump procedure is a frequency modulation technique between two discrete frequencies at the inflection points at both sides of the NV ODMR resonance, which yields a signal proportional to the temperature shift over a wide temperature range. The approach is generic and is demonstrated by time-dependent measurements of the local temperature at different spots on a microelectronics circuit under electrical switching operation of one of the devices. | Keywords: | temperature sensing;ODMR;frequency modulation;microelectronic device;time dependence | Document URI: | http://hdl.handle.net/1942/34030 | ISSN: | 0957-4484 | e-ISSN: | 1361-6528 | DOI: | 10.1088/1361-6528/ab5a0c | ISI #: | WOS:000515105000001 | Rights: | 2019 IOP Publishing Ltd Printed in the UK | Category: | A1 | Type: | Journal Contribution | Validations: | ecoom 2021 |
