Development of a xenon triple point apparatus suitable for calibrating long-stem SPRTs and preliminary measurements of the temperature
Yikun Zhao, Jintao Zhang, Xiaojuan Feng +5
Xenon is of high chemical-physical stability and health compatibility. The xenon triple point (Xe TP) is accounted for a promising candidate replacing the mercury triple point (Hg…
Red-shift effect on the zero field splitting for negatively charged nitrogen-vacancy centers in diamond
Wang Zheng, Zhang Jintao, Feng Xiaojuan +1
The zero field splitting (ZFS) quantifies the energy difference for the ground electron spin-triplet of a nitrogen-vacancy center in the absence of external fields. The values of t…
Temperature sensing using nitrogen-vacancy centers with multiple-poly crystal directions based on Zeeman splitting
Li Xing, Xiaojuan Feng, Jintao Zhang +1
We demonstrate a novel method based on the Zeeman splitting of electronic spins to improve the performance for temperature sensing of negatively-charged nitrogen-vacancy (NV) cente…
Microwave heating effect on diamond sample of NV centers
Zheng Wang, Jintao Zhang, Xiaojuan Feng +1
Diamond samples of defects with negative charged nitrogen-vacancy (NV) centers are promising solid state spin sensors suitable for quantum information processing, high sensitive me…
Temperature dependence of nitrogen-vacancy center ensembles in diamond based on an optical fiber
Ke-Chen Ouyang, Zheng Wang, Li Xing +4
The nitrogen-vacancy (NV) centers in diamond sensing has been considered to be a promising micro-nano scale thermometer due to its high stability, good temperature resolution and i…
Determination of the Boltzmann Constant Using the Differential - Cylindrical Procedure
X. J. Feng, J. T. Zhang, H. Lin +2
We report in this paper the progresses on the determination of the Boltzmann constant using the acoustic gas thermometer (AGT) of fixed-length cylindrical cavities. First, we prese…
