Photosystem 1 (PS1) triggers the most energetic light-induced charge-separation step in nature and the in vivo electron-transfer rates approach 50 e(-) s(-1) PS1(-1). Photoelectrochemical devices based on this building block have to date underperformed with respect to their semiconductor counterparts or to natural photosynthesis in terms of electron-transfer rates. We present a rational design of a redox hydrogel film to contact PS1 to an electrode for photocurrent generation. We exploit the pH-dependent properties of a poly(vinyl)imidazole Os(bispyridine)2Cl polymer to tune the redox hydrogel film for maximum electron-transfer rates under optimal conditions for PS1 activity. The PS1-containing redox hydrogel film displays electron-transfer rates of up to 335±14 e(-) s(-1) PS1(-1), which considerably exceeds the rates observed in natural photosynthesis or in other semiartificial systems. Under O2 supersaturation, photocurrents of 322±19 μA cm(-2) were achieved. The photocurrents are only limited by mass transport of the terminal electron acceptor (O2). This implies that even higher electron-transfer rates may be achieved with PS1-based systems in general.

Two-dimensional materials have been extensively applied because of their unusual electronic, mechanical, and optical properties. In this paper, the electronic structure and optical properties of Hf 2 CO 2 MXene under biaxial and uniaxial strains are investigated by the Heys-Scuseria-Ernzerhof (HSE06) method. Monolayer Hf 2 CO 2 can sustain stress up to 6.453 N/M for biaxial strain and 3.072 N/M for uniaxial strain. Monolayer Hf 2 CO 2 undergoes the transition from semiconductor to metal under −12% strain whether it is under biaxial or uniaxial strain. With the increasing biaxial compressive strain, the blue shift of Hf-d, O-p, and C-p orbitals in valence band maximum results in the metallization of monolayer Hf 2 CO 2 , while the red shift of Hf-d and O-p orbitals in conduction band minimum results in the metallization of monolayer Hf 2 CO 2 with increasing uniaxial compressive strain. The analysis of optical properties indicates that uniaxial strain weakens the reflectivity and refractive index of monolayer Hf 2 CO 2 in the visible-light range. In addition, the effective mass and the charge distribution under biaxial and uniaxial strains are also explored.

“…It can be seen from Figure that the CBM of monolayer Ga 2 O 3 at the Γ point is composed of the σ* anti‐bonding between O‐s, p z orbitals, and Ga‐s orbitals. In general, the σ* anti‐bonding is pushed up and down by increasing tensile and compressive strain, respectively . Thus, the energy of CBM at the Γ point is increased and reduced by increasing tensile and compressive strain.…”

The discovery of two-dimensional (2D) Ga 2 O 3 has provided an effective way to further tune the performance of β-Ga 2 O 3 . Understanding the effects of strain and electric field (E-field) on 2D Ga 2 O 3 is helpful to explore the mechanism and potential application in the flexible device. Here, transport and optical properties of monolayer Ga 2 O 3 under uniaxial strain and E-field are investigated. An indirect-to-direct band-gap-transition occurs under uniaxial tension due to the different variation of π bonding at the valence bands. The band-gap exhibits a parabolic variation character from compression to tension, and relates to the direction of uniaxial strain. Interestingly, the transport characters are sensitive to the direction of uniaxial strain, and both compression and tension along b direction enhance the mobility of monolayer Ga 2 O 3 , which is inconsistent with that of electron effective mass. The mobility of tensile monolayer Ga 2 O 3 can be enlarged to 48368.14 cm 2 V −1 s −1 , different to that of 2D layered materials. Interestingly, the ultra-visible absorption coefficients are just enhanced significantly by compression along c direction. Upon monolayer Ga 2 O 3 undergoes large E-field (>0.5 eVÅ −1 ), the band-gap and anisotropic transport property decreases and even vanishes. The results are useful to reveal the mechanisms and potential of 2D Ga 2 O 3 in the flexible devices.
