Quantum Sensor for Nanoscale Defect Characterization

Quantum Zeno Isolation of Quantum Dots

“…A frequently discussed decoherence mechanism is the scattering of the electrons or holes in the reservoir at local impurities. As long as these impurities (which can be characterized experimentally [44]) are not too dense and thus far away from the dot, this mechanism is not relevant here because, as explained above, if the reservoir wave packet moved away from the dot far enough to see the impurity, it is already outside the region of applicability of the quantum Zeno effect. Another potentially important mechanism stems from the Coulomb interaction between the electrons or holes or their interaction with phonons.…”

Highly anisotropic and ultra-diffusive vacancies in α-antimonene

“…, electrocatalytic hydrogen evolution, gas sensors, spintronics, multiferroics, memristive devices, etc . 24–36 For 2D elemental materials ( e.g. , phosphorene, graphene, and silicene) with honeycomb-like structures, known point defects include the Stone–Wales (SW), single vacancy (SV), and double vacancy (DV) defects, which have been extensively investigated.…”

“…Hence, the defect-dependent structural, physical, and chemical properties can be exploited for various applications, e.g., electrocatalytic hydrogen evolution, gas sensors, spintronics, multiferroics, memristive devices, etc. [24][25][26][27][28][29][30][31][32][33][34][35][36] For 2D elemental materials (e.g., phosphorene, graphene, and silicene) with honeycomb-like structures, known point defects include the Stone-Wales (SW), single vacancy (SV), and double vacancy (DV) defects, which have been exten-sively investigated. 24,25,[37][38][39][40] Among them, the SW defect has been viewed as the most popular defect in 2D elemental sheets because it generally entails the lowest formation energy (E f ).…”

Post-processing of real-time quantum event measurements for an optimal bandwidth

“…For example, in the fabrication of ever smaller transistor structures, the charge quantization is becoming increasingly important [1]. Also, a deeper understanding of quantum transport [2] could give new insights for current issues, such as the fast readout of various qubit candidates [3,4] or quantum sensing [5,6]. The tunneling of single electrons can be studied using the random telegraph signal (RTS), where the state of a quantum system is measured in real-time and the quantum mechanical fluctuations can be statistically evaluated [7][8][9].…”
