Continuously tunable electronic structure of transition metal dichalcogenides superlattices

Scientific Reports (2015)

Yong-Hong Zhao Feng Yang Jian Wang Hong Guo Wei Ji

Two dimensional transition metal dichalcogenides have very exciting properties for optoelectronic applications. In this work we theoretically investigate and predict that superlattices comprised of MoS2 and WSe2 multilayers possess continuously tunable electronic structure with direct bandgaps. The tunability is controlled by the thickness ratio of MoS2 versus WSe2 of the superlattice. When this ratio goes from 1:2 to 5:1, the dominant K-K direct bandgap is continuously tuned from 0.14 eV to 0.5 eV. The gap stays direct against -0.6% to 2% in-layer strain and up to -4.3% normal-layer compressive strain. The valance and conduction bands are spatially separated. These robust properties suggest that MoS2 and WSe2 multilayer superlattice should be a promising material for infrared optoelectronics.

Electronic evidence of temperature-induced Lifshitz transition and topological nature in ZrTe5

Nature Communications (2017)

Yan Zhang Chenlu Wang Li Yu Guodong Liu Aiji Liang

The topological materials have attracted much attention for their unique electronic structure and peculiar physical properties. ZrTe5 has host a long-standing puzzle on its anomalous transport properties manifested by its unusual resistivity peak and the reversal of the charge carrier type. It is also predicted that single-layer ZrTe5 is a two-dimensional topological insulator and there is possibly a topological phase transition in bulk ZrTe5. Here we report high-resolution laser-based angle-resolved photoemission measurements on the electronic structure and its detailed temperature evolution of ZrTe5. Our results provide direct electronic evidence on the temperature-induced Lifshitz transition, which gives a natural understanding on underlying origin of the resistivity anomaly in ZrTe5. In addition, we observe one-dimensional-like electronic features from the edges of the cracked ZrTe5 samples. Our observations indicate that ZrTe5 is a weak topological insulator and it exhibits a tendency to become a strong topological insulator when the layer distance is reduced.

Nonvolatile modulation of electronic structure and correlative magnetism of L10-FePt films using significant strain induced by shape memory substrates

Scientific Reports (2016)

Chun Feng Jiancheng Zhao Feng Yang Kui Gong Shijie Hao

Abstract Tuning the lattice strain (ε L ) is a novel approach to manipulate the magnetic, electronic and transport properties of spintronic materials. Achievable ε L in thin film samples induced by traditional ferroelectric or flexible substrates is usually volatile and well below 1%. Such limits in the tuning capability cannot meet the requirements for nonvolatile applications of spintronic materials. This study answers to the challenge of introducing significant amount of elastic strain in deposited thin films so that noticeable tuning of the spintronic characteristics can be realized. Based on subtle elastic strain engineering of depositing L1 0 -FePt films on pre-stretched NiTi(Nb) shape memory alloy substrates, steerable and nonvolatile lattice strain up to 2.18% has been achieved in the L1 0 -FePt films by thermally controlling the shape memory effect of the substrates. Introduced strains at this level significantly modify the electronic density of state, orbital overlap and spin-orbit coupling (SOC) strength in the FePt film, leading to nonvolatile modulation of magnetic anisotropy and magnetization reversal characteristics. This finding not only opens an efficient avenue for the nonvolatile tuning of SOC based magnetism and spintronic effects, but also helps to clarify the physical nature of pure strain effect.

Fast synthesis of β-NaYF₄:Ln³⁺(Ln = Yb/Er, Yb/Tm) upconversion nanocrystals via a topotactic transformation route

CrystEngComm (2016)

Feng Yang Baiqi Shao Yan Song Shuang Zhao Jiansheng Huo

Monodisperse β-NaYF4:Ln3+ (Ln = Yb/Er, Yb/Tm) upconversion nanocrystals have been fast synthesized using layered yttrium hydroxide Y2(OH)5NO3·nH2O (LYH) via a topotactic transformation route bypassing the α-NaYF4 intermediate phase. It was found that the topotactic structural matching of [001]LYH//[0001]β-NaYF4 facilitated the direct formation of β-NaYF4, wherein the kinetic α-NaYF4 intermediate phase could be avoided at the initial reaction stage. Besides, the morphology could be effectively tuned by manipulating the NaF/Y(NO3)3 feeding ratio. In addition, the upconversion luminescence properties of the as-prepared β-NaYF4:15%Yb3+/2%Er3+ and β-NaYF4:15%Yb3+/1%Tm3+ were also systematically investigated.
