HIGHLIGHTED ARTICLES

Skyrmion-Based Programmable Logic Device with Complete Boolean Logic Functions

Z.R. Yan, Y.Z. Liu, Y. Guang, K. Yue, J.F. Feng, R.K. Lake, G.Q. Yu, and X.F. Han

Phys. Rev. Applied 15, 064004 (2021) - Published 2 June, 2021

The memory wall, a bottleneck between storage and processor in the traditional von Neumann computing paradigm, has become increasingly serious with the rise of “Big Data”, and there is strong interest in developing logic-in-memory computing architectures. The authors propose a skyrmion-based programmable logic device with complete Boolean logic functions, a feature that has remained elusive so far. This device can realize robust and programmable logic functions under solely electrical control, in the presence of both the inhomogeneities and thermal fluctuations that are are experimentally unavoidable. This result, then, suggests a path to overcoming the memory wall.

Temperature-Dependent Charge-Transfer-State Absorption and Emission Reveal the Dominant Role of Dynamic Disorder in Organic Solar Cells

Clemens Göhler, Maria Saladina, Yazhong Wang, Donato Spoltore, Johannes Benduhn, Karl Leo, and Carsten Deibel

Phys. Rev. Applied 15, 064009 (2021) - Published 3 June, 2021

In organic photovoltaics, the energetic characteristics of the charge-transfer state determine the device properties, and are defined by molecular interactions at the donor-acceptor interface. This study uses sensitive spectroscopy to investigate the roles of morphological disorder and molecular dynamics in charge-transfer states, which ultimately affect the open-circuit voltage. The authors model temperature-dependent data and find that dynamic, rather than static, disorder determines the optical properties of the charge-transfer states. Thus, to develop highly efficient organic solar cells, the intramolecular properties of the working materials should receive more attention.

Electrical Tuning of Tin-Vacancy Centers in Diamond

Shahriar Aghaeimeibodi, Daniel Riedel, Alison E. Rugar, Constantin Dory, and Jelena Vučković

Phys. Rev. Applied 15, 064010 (2021) - Published 3 June, 2021

Many applications in quantum information processing require multiple, identical quantum emitters. Among various color centers in diamond, tin-vacancy centers draw attention because of their high quantum efficiency and long spin coherence. The authors study the shifts of optical-transition frequencies of these centers in an applied electric field, and importantly find that both the linear and quadratic coefficients are orders of magnitude smaller than those of non-inversion-symmetric defects such as nitrogen-vacancy centers. This low susceptibility allows the integration of tin-vacancy centers into photonic nanostructures, which is essential for efficient spin-photon interfaces.

Voltage-Gate-Assisted Spin-Orbit-Torque Magnetic Random-Access Memory for High-Density and Low-Power Embedded Applications

Y.C. Wu, K. Garello, W. Kim, M. Gupta, M. Perumkunnil, V. Kateel, S. Couet, R. Carpenter, S. Rao, S. Van Beek, K.K. Vudya Sethu, F. Yasin, D. Crotti, and G.S. Kar

Phys. Rev. Applied 15, 064015 (2021) - Published 7 June, 2021

To address the large energy dissipation of our current computing architecture, nonvolatile voltage-gate-assisted spin-orbit-torque (VGSOT) MRAM combines the advantages of spin-orbit-torque (SOT) and voltage control of magnetic anisotropy (VCMA) systems. Here the authors study VGSOT writing with perpendicular magnetic tunnel junctions, and show it to be reliable, with low error rate and resilience to intensive writing stresses. The spin Hall angle and VCMA coefficient allow 30-nm junctions. A multipillar design is suggested, with high density close to 2-terminal devices and high-speed write/read performance at low operating power, suitable for embedded memory or in-memory computation.

Charge-Collection Efficiency in Back-Illuminated Charge-Coupled Devices

Guillermo Fernandez Moroni, Kevin Andersson, Ana Botti, Juan Estrada, Dario Rodrigues, and Javier Tiffenberg

Phys. Rev. Applied 15, 064026 (2021) - Published 10 June, 2021

Charged-coupled devices (CCDs) are among the most promising technologies to enable experiments in the direct search for low-mass dark matter, and a new generation of compact neutrino detectors. Understanding the charge-collection efficiency of these detectors is a limiting factor for current and future experiments. The authors present a technique to characterize and measure the efficiency as a function of the charge-generation depth, with submicrometer precision. Using these tools, they furthermore compare the performance of two different back-side treatments and discuss the implications for CCD research and development.

Universal Model for Predicting the Thermal Boundary Conductance of a Multilayered-Metal–Dielectric Interface

Henry T. Aller, Jonathan A. Malen, and Alan J.H. McGaughey

Phys. Rev. Applied 15, 064043 (2021) - Published 17 June, 2021

Overheating in electronic devices is difficult to mitigate, because thermal transport across the internal interfaces is poorly understood. This study uses atomistic simulations and analytical theory to create a model that predicts how the thermal boundary conductance of a metal cap–metal contact–dielectric junction varies with contact thickness. The model contains no fitting parameters and is validated against more than 100 experimental measurements, revealing the important role played by electron-phonon coupling. Physically motivated approximations reduce the model to a simple thermal circuit that retains high predictive power, for streamlining the design of thermally efficient contacts.

Molecular-Spin-Qubit Noise Spectroscopy Through Dynamical Decoupling

Yue Fu, Yang Wu, Yingqiu Dai, Xi Qin, Xing Rong, and Jiangfeng Du

Phys. Rev. Applied 15, L061001 (2021) - Published 24 June, 2021

With the power of chemistry for inexpensive synthesis of tailored systems, molecular qubits are attractive candidates for quantum computing. Here decoherence persists as a major obstacle; for its effective suppression, the properties of environmental noise must be elucidated. Traditional noise spectroscopy with spurious harmonics leads to false identification of nuclear spins. The authors demonstrate a protocol for noise-spectrum analysis without spurious harmonics, through dynamical decoupling. This result enables enhanced coherence for molecular qubits, and could be quite significant for quantum information processing based on such systems.

Low-resistance ohmic contacts are a prerequisite for implementing two-dimensional transition-metal dichalcogenides (2D TMDs) in a host of applications. Edge contacts offer unique advantages, yet their electrical properties are not fully understood. Employing an ab initio framework, the authors find that edge contacts to monolayer MoS2 are pinned to a charge-neutrality level close to the valence band and are p-type—unlike typical n-type top contacts. This anisotropy in Fermi-level pinning complicates conduction through metal-TMD interfaces and affects design guidelines for low-resistance contacts. Challenges, potential mitigating solutions, and opportunities that leverage this anisotropy are discussed.
