  • Publication number: 20250127062
    Abstract: A voltage-controlled three-terminal magnon transistor is provided, including a ferroelectric layer, a magnetic layer, a generation terminal, a control terminal, a detection terminal, and a bottom electrode. After a current is inputted into the generation terminal, a magnon is generated in the magnetic layer. The detection terminal is made of a heavy metal material, which can convert the magnon in the magnetic layer into a charge flow. When a voltage pulse applied between the control terminal and the bottom electrode exceeds a critical value, non-volatile polarization and non-volatile strain states of the ferroelectric layer change, which in turn affects a transmission capability of the magnon in the magnetic layer based on a magnetoelectric coupling effect between the ferroelectric layer and the magnetic layer. In addition, a voltage signal of the detection terminal exhibits a regular loop change behavior with a change of the voltage pulse.

  • Patent number: 12278660
    Abstract: Provided is a pattern division multiple access (PDMA) communication system based on optimal frequency-hopping patterns, which includes a transmitter and a receiver. The transmitter modulates an input baseband signal into a modulated signal, and then converts the modulated signal into a signal that hops in frequency according to the optimal frequency-hopping pattern. The receiver reverts the received frequency-hopping signal to an output modulated signal using an optimal frequency-hopping pattern same as that of the transmitter, and then demodulates the modulated signal into a baseband signal. The optimal frequency-hopping patterns are obtained by applying two-dimensional cyclic shift to a Golomb Costas array constructed based on an extension field, and thus are frequency-hopping patterns with ideal autocorrelation and cross-correlation properties.

  • Publication number: 20250098396
    Abstract: The invention relates to a perovskite solar cell modified by a chelating layer and its preparation method, within the field of perovskite material preparation. The process involves spin-coating N, N?-bis(4-pyridyl)-1,4,5,8-naphthalenetetracarboxylic diimide (DPNDI) solution on the perovskite surface, followed by annealing. This modification forms a chelating structure on the surface, passivating defect sites and grain boundaries, promoting charge transfer with optimized energy levels and carrier mobility. The Pb (II) coordination polymer layer enhances bonding strength and adhesion, effectively suppressing traps. The treated perovskite solar cell achieves a photoelectric conversion efficiency (PCE) of 24.2%, with a T80 lifetime retaining over 95% (40° C.) and 85% (85° C.) of the initial PCE after 2000 hours.
