P3LI5: Practical and confidEntial Lawful Interception on the 5G core

Lawful Interception (LI) is a legal obligation of Communication Service Providers (CSPs) to provide interception capabilities to Law Enforcement Agencies (LEAs) in order to gain insightful data from network communications for criminal proceedings, e.g., ne ...

Solids that are also liquids: elastic tensors of superionic materials

Nicola Marzari, Tommaso Chiarotti, Giuliana Materzanini

Superionics are fascinating materials displaying both solid- and liquid-like characteristics: as solids, they respond elastically to shear stress; as liquids, they display fast-ion diffusion at normal conditions. In addition to such scientific interest, su ...

Lateral ion migration accelerates degradation in halide perovskite devices

Christophe Ballif, Quentin Thomas Jeangros, Christian Michael Wolff, Daniel Anthony Jacobs, Kerem Artuk, Xin Yu Chin

The migration of mobile ions has long been considered a source of performance degradation in devices based on halide perovskites, but details regarding the mechanisms and extent of this problem remain scarce. Here we report the finding that differences in ...

Assessing mobile ions contributions to admittance spectra and current-voltage characteristics of 3D and 2D/3D perovskite solar cells

Mohammad Khaja Nazeeruddin, Sanghyun Paek, Zubair Ahmad

Recently, the 2D perovskite layer is employed as a capping/passivating layer in the perovskite solar cells (PSCs). The 2D perovskite layer is prepared by inserting a large-sized hydrophobic cation spacer into the perovskite crystal lattice. The large-sized ...

Understanding Heavy Drinking at Night through Smartphone Sensing and Active Human Engagement

Daniel Gatica-Perez, Skanda Muralidhar, Thanh Trung Phan

Heavy alcohol consumption can lead to many severe consequences. In this paper, we study the phenomenon of heavy drinking at night (4+ drinks for women or 5+ for men on a single evening), using a smartphone sensing dataset depicting about nightlife and drin ...

Unsupervised landmark analysis for jump detection in molecular dynamics simulations

Nicola Marzari, Boris Kozinsky, Leonid Kahle, Albert Daniel Musaelian

Molecular dynamics is a versatile and powerful method to study diffusion in solid-state ionic conductors, requiring minimal prior knowledge of equilibrium or transition states of the system's free energy surface. However, the analysis of trajectories for r ...

Electroluminescence Dynamics in Perovskite Solar Cells Reveals Giant Overshoot Effect

Wolfgang Richard Tress, Marius Franckevicius

High performance of both photovoltaic and electroluminescent devices requires low nonradiative recombination losses. In perovskites, such loses strongly depend on the carrier traps related to the mobile ions and vacancies, causing I-V hysteresis of solar c ...

How the formation of interfacial charge causes hysteresis in perovskite solar cells

Michael Graetzel, Wolfgang Richard Tress, Ulf Anders Hagfeldt, Silver Hamill Turren Cruz

In this study, we discuss the underlying mechanism of the current-voltage hysteresis in a hybrid lead-halide perovskite solar cell. We have developed a method based on Kelvin probe force microscopy that enables mapping charge redistribution in an operating ...
