Electronic structures and magnetic properties of CrSiTe3 single-layer nanoribbons

In this study, we systematically investigate the stability, electronic structures and magnetic properties of CrSiTe3 single-layer nanoribbons with different edge configurations and ribbon widths using first-principles calculations. The results show that the edge energies (less than 0.4 eV/Å) for all studied CrSiTe3 nanoribbons are much lower than that of graphene and many transition-metal dichalcogenide nanoribbons, indicating their stability and easy formation. Compared to the CrSiTe3 monolayer with ferromagnetic semiconductor characterictics, some of CrSiTe3 nanoribbons (N-SiCr-ZNRs, N-Te-ZNRs, N-TeCr-ANRs and N-Te-ANRs) become half-metal due to the hybridization between the d orbitals of edge Cr atoms and the p orbitals of edge Te atoms. While N-SiTe-ANRs are bipolar magnetic semiconductors, in which the states near Fermi level are localized around the nanoribbons edge. Our results show that CrSiTe3 single-layer nanoribbons are promising candidates suitable for applications in spintronic devices.

In this work, we firstly studied the effect of the iR drop between the BPE cathode and anode on the electrochemical performance of a closed BPE device. Due to the significant iR loss between the two poles of the BPE, an increased external voltage, applied on the driving electrodes, was required to ...

IntroductionDepressive and manic episodes of bipolar disorder can interact with sleep complaints, followed by a worsened psychiatric condition. The aim of this study was to examine the interaction of sleep disorders with bipolar disorder in youths during depressive and manic episodes.MethodsThe target population was children and adolescents drawn from the Children and Adolescents Affective Disorder Program. Clinical assessment for current psychiatric diagnosis was done by direct clinical interview, Diagnostic Interview for Children and Adolescents (DSM-IV), and best-estimated clinical consensus. We applied sleep questionna...

Mental health issues affect billions of people across every corner of the globe, touching every community and every family, and mounting evidence shows the issue is worsening. To combat the issue, we need to urgently grow our investment in programs that expand access to care, mental health advocates said at a TIME lunch on Wednesday in Davos, Switzerland. “Invest in the system, invest in our rights,” said Elisha London, founder and CEO of United for Global Mental Health. She called for $1 billion in spending on mental health programs worldwide: “It has to happen now.” The event, held during the annu...

To examine the functional substitutability of Otx2 and Crx, we generate knockin mouse lines in which Crx is replaced by Otx2 and vice versa. We find that Otx2 and Crx cannot be substituted in photoreceptor development. Subsequently, we investigate the function of O...
