Ag^＋ -doped ZnS nanocrystals surface-capped with thiourea （expressed as ZnS： Ag/thiourea） were synthesized through sol-gel method with thiourea as a surface modifier and characterized by X-ray diffraction（XRD）, transmission electron microscope（TEM）, X-ray fluorescence spectrum（XRF）, infrared spectrum （IR）, UV-Vis absorption spectrum（ UV-Vis）, and photoluminescence spectrum（PL）. The results show that Ag^＋ ions are doped in ZnS nanocrystals, and the sulfur atoms in thiourea molecules coordinate with metal ions on the surface of the nanocrystals. The spherical ZnS： Ag/thiourea nanocrystals with an average diameter of 5 nm have good fluorescent characteristics, and therefore have great potential for use in molecular assembly and novel luminescence materials.

Tunneling FET（TFET） is considered as one of the most promising low-power electronic devices,however, suffers from the low drive current. Heterostructure TFET with low effective tunnel barrier height based on traditional 3D materials can obtain large tunnel current but deteriorated off-state current induced by the lattice mismatch. van der Waals heterostructure TFET based on 2D materials can obtain danglingbond-free interface for suppressed off-state current but face the challenge of controllable and stable doping technology. As the critical building block of the TFET, tunnel diode based on the 2D/3D heterostructure is proposed in this study and experimentally demonstrated. Combination of the pristine interface of 2D materials and matured doping technology in the traditional 3D bulk materials, tunnel diodes based on the 2D/3D heterostructures are expected to realize low leakage current and high on current simultaneously,showing great potential in low-power electronics. The N+SnS2/P+Si heterostructure with effective tunnel barrier of 0.17 eV theoretically is considered for the first time and selected as the optimal material platform for tunnel diodes. The N+SnS2/P+Si tunnel diode demonstrated experimentally shows the high current density of 1 μA/μm2, which is the highest one among the reported tunnel diodes based on the 2D/group IV materials. The tunneling current is also confirmed by low-temperature measurements. This study shows the great potential of the 2D/3D heterostructure for low-power tunneling devices.

It was first proposed that an extended chain Ising （ECI） model contains the Ising chain model, single spin doublewell potentials and a pure phonon heat bath of a specific energy exchange with the spins. The extension method is easy to apply to high dimensional cases. Then the single spin-flip probability （rate） of the ECI model is deduced based on the Boltzmann principle and general statistical principles of independent events and the model is simplified to an extended chain Glauber-Ising （ECGI） model. Moreover, the relaxation dynamics of the ECGI model were simulated by the Monte Carlo method and a comparison with the predictions of the special chain Clauber-Ising （SCGI） model was presented. It was found that the results of the two models are consistent with each other when the Ising chain length is large enough and temperature is relative low, which is the most valuable case of the model applications. These show that the ECI model will provide a firm physical base for the widely used single spin-flip rate proposed by Glauber and a possible route to obtain the single spin-flip rate of other form and even the multi-spin-flip rate.
