Simulation analysis and their implication
Two-dimensional schematic and simulation models for distant structures are depicted in Fig. 2. Under the conditions of Ue = 120 V, Uc = 10 V, and d = 120 μm, the analysis revealed a uniform…

Baseband control of single-electron silicon spin qubits in two dimensions
Device design and fabrication
The device layout used in this work are similar to the ones used in our previous work26. The heterostructure comprises a Si0.69Ge0.31 strained relaxed buffer (SRB), a 7 nm tensile-strained 28Si quantum well (isotopic…

Silicon nano-kirigami with controlled plastic, elastic and hysteretic deformations
Nano-kirigami on SOI
Here a commercial SOI wafer is used as the silicon-based platform, which consists of three layers: a Si device layer (with thickness t), a buried SiO2 layer, and a Si substrate layer (750 µm in thickness). As illustrated in…

Pseudo-Landau levels splitting triggers quantum friction at folded graphene edge
Construction of folded graphene
To achieve graphene folding, monolayer and multilayer graphene flakes were mechanically exfoliated onto a Si/SiO2 substrate. By lateral scanning with an applied normal load at the atomic force microscope (AFM) tip,…

Edge-feeding synchronous epitaxy of layer-controlled graphene films on heterogeneous catalytic substrates
Synchronous epitaxial growth strategy
Figure 1a depicts the process of edge-feeding synchronous growth of trilayer graphene, facilitated by heterogeneous Cu–Cu2O substrates. The Cu substrate serves both as a supporting platform and as the raw…

Deterministic generation of two-dimensional multi-photon cluster states
Device architecture and cluster state generation protocol
To generate ladder-like cluster states, we use two transmon qubits whose lowest three levels we label \(\vert g\rangle\), \(\vert e\rangle\) and \(\vert \, f\rangle\), tunably coupled to…
