Advanced Functional Materials, EarlyView.A 6‐in wafer‐scale atomic‐layer‐controlled tungsten disulfide (WS2) is achieved by combining plasma‐assisted synthesis with three‐gas reactive ion etching. Precise layer control enables tunable band‐gap evolution and pulse‐history‐dependent opto‐memristive dynamics.

Advanced Functional Materials, EarlyView.Cuttlefish and squid can catch their prey within milliseconds using specialized tentacles and suckers. The physics of how the suckers can attach so quickly has remained a mystery given the technical challenges of studying them in vivo. In this publication, we develop a hydrogel that retains imprints of the suckers in order to estimate the forces they ...

Minimal Energy Tree with 4 Branched Vertices
Open Chemistry, 2019 The energy of a graph is defined as the sum of absolute values of the eigenvalues of its adjacency matrix. Let Ω(n,4) be the class of all trees of order n and having 4 branched vertices. In this paper, the minimal energy tree in the class Ω(n,4) is found.

The Characteristic Polynomial And Its Applications [PDF]
This dissertation examines some applications of the characteristic polynomial \[Q_A(z):=\det (z_0I+z_1A_1+\cdots+z_nA_n),\] where $A_0,\dots,A_n$ are complex square matrices and $(z_0,\dots,z_n)\in\mathbb{C}^{n+1}$.

Universal Conductance Fluctuations in Quantum Anomalous Hall Insulators
Advanced Materials, EarlyView.Universal conductance fluctuations are observed in mesoscopic quantum anomalous Hall insulators. Two distinct fluctuation patterns are identified, arising from different interference processes of bulk and chiral edge states, respectively. These findings unveil rich quantum interference phenomena in quantum anomalous Hall insulators and provide insights

Advanced Materials, EarlyView.Anion‐exchange doping of conjugated polymers is an effective way to achieve high conductivities. Here, we report over 2000 S cm−1 electrical conductivity for doped P(g3BTTT). In addition, we show that P(g3BTTT) sustains exceptionally high doping levels without any drop in the charge mobility.

Spin Transport Across Interfaces With the Non‐Collinear Antiferromagnet Mn3Sn
Advanced Materials, EarlyView.We study spin transport with Mn3Sn|Metal${\rm Mn}_3{\rm Sn}\vert{\rm Metal}$ heterostructures. For Mn3Sn|Pt${\rm Mn}_3{\rm Sn}\vert{\rm Pt}$ heterostructures, ultrafast spin current generation by optical pumping of Mn3Sn${\rm Mn}_3{\rm Sn}$ is explored, while for Mn3Sn|NiFe${\rm Mn}_3{\rm Sn}\vert{\rm NiFe}$ heterostructures, we probe the spin–charge ...
