Shandong University has proposed a new growth method that enables the fabrication of gallium-based semiconductors on various substrates.​


Shandong University has introduced a groundbreaking growth method known as "Induced Fit Growth," which facilitates the fabrication of gallium-based semiconductors on diverse substrates without strict lattice matching requirements. Collaborating with City University of Hong Kong and Kyushu University, the research team developed this technique to overcome historical limitations in growing high-quality semiconductor thin films. By utilizing amorphous gallium oxide (GaOx) templates, the method allows for ordered crystal formation on a wider range of materials, effectively removing cost barriers that previously restricted the adoption of advanced 32-bit semiconductor technologies.

The core mechanism draws inspiration from biological systems, where enzymes guide polypeptide chains into functional structures rather than disordered shapes. In this context, localized gallium regions within the amorphous GaOx films act as nucleation sites, inducing the orderly arrangement of group V elements to form crystalline compounds like gallium antimonide (GaSb). This process enables high-quality crystal growth on previously incompatible substrates, demonstrating that even non-crystalline templates can serve as effective foundations for complex semiconductor structures when specific chemical conditions are met.

Experimentally, the team successfully prepared various gallium-based thin films, including GaSb, GaSe, and GaAsSb alloys, using a dual-temperature horizontal tube furnace with liquid metal exfoliation to create uniform GaOx templates. Analysis revealed that traditional spin-coating methods failed to replicate these results because they lack the necessary gallium-rich regions required for crystal initiation. Instead, the unique properties of the liquid-metallurgy-derived films allowed for "seeds" that promoted island-like growth structures which eventually expanded and interconnected to form dense, continuous layers comparable in mechanism to traditional epitaxial lateral growth (ELO).

Beyond material fabrication, this innovation has yielded significant advancements in device applications, particularly in flexible electronics and neuromorphic computing. Researchers utilized the GaSb thin films to construct transistors that mimic biological neural synapses, exhibiting plasticity behaviors similar to double-pulse facilitation and time-dependent synaptic functions
. Additionally, an infrared photodetector based on these materials demonstrated exceptional performance with high photoresponsivity in the 800–1550 nm range, paving the way for future developments in omnidirectional light sensing and imaging arrays across various substrate platforms.​

Generation of deep-sub-cycle optical pulses via inverse Compton scattering in a mid-infrared laser field​

Sub-cycle optical pulses with extremely high temporal gradients represent a forefront direction in ultrafast science. Although such pulses can provide ultrahigh temporal resolution for probing ultrafast dynamics, the ultimate half-cycle limit of pulse duration (i.e., pulse width smaller than half an optical cycle) has remained unbroken. To address this challenge, we recently proposed a scheme to generate deep-sub-cycle optical pulses via inverse Compton scattering (ICS) between a relativistic electron bunch and a deep-subwavelength confined terahertz (THz) optical field. Here, we extend this concept by replacing the THz field with a mid-infrared deep-subwavelength confined optical field, which can significantly enhance the energy of the emitted photons with similar electron-bunch incidence. For instance, when a 2-MeV, 50-as electron bunch interacts with a mid-infrared confined field with a peak wavelength of 4.4 μm and a pulse duration of 100 fs, the ICS process can generate a 0.26-cycle, 99-as extreme-ultraviolet (EUV) unipolar pulse with a peak frequency of 2.6 PHz. A trade-off between the temporal confinement and single-pulse photon number is also discussed.​

Silan Microelectronics signed a supplementary agreement for its 12-inch chip production line project, introducing new investors to accelerate project construction.​


Silan Microelectronics has officially signed a supplementary investment agreement with three new local investors to accelerate the construction of its 12-inch high-end analog integrated circuit chip manufacturing production line in Xiamen. The deal involves significant capital injection totaling RMB 3.6 billion, which will be directed toward the project company, Xiamen Silan Jihua Microelectronics Co., Ltd. The new investors include Xiamen Haixia Liantou Investment Partnership, which steps in to take over the original obligations of Xiamen Semiconductor Investment Group; and two additional partnerships, Xinyi Xincheng and Chantou Xinhua, which assume RMB 2.1 billion collectively from Xinyi Technology's prior commitment.

Following this capital increase, Silan Microelectronics' registered capital will rise to RMB 5.11 billion. The equity structure will be adjusted so that Silan Microelectronics retains a 29.55% stake by contributing RMB 1.51 billion, while the new investors collectively hold the remaining 70.45%. Specifically, Haixia Liantou is set to own 29.35% of the shares with a RMB 1.5 billion contribution, and each of Xinyi Xincheng and Chantou Xinhua will hold 20.55% with RMB 1.05 billion contributions respectively. This round of investment marks Silan Microelectronics' first step in what is expected to be a larger capital expansion to RMB 6.01 billion, further diluting its shareholding to approximately 25%.

A crucial aspect of this restructuring is the change in how Silan Microelectronics accounts for its subsidiary, Jihua. Prior to this investment, Silan held a 100% stake and consolidated all financial results from Jihua into its own statements. After the transaction completes, Silan's shareholding will drop to 29.55%, causing it to cease consolidating Jihua's finances. Instead, the subsidiary will be accounted for using the equity method, with investment income recognized based on this new partial ownership ratio.

Company officials stated that introducing these strategic partners and optimizing the equity structure is essential for speeding up the long-term construction of the 12-inch production line. By leveraging its unique advantages in the integrated design and manufacturing (IDM) model, Silan aims to enhance its core competitiveness in high-end analog chips. This move is also designed to position the company better to capitalize on emerging opportunities in industries such as new energy vehicles, computing servers, and robotics, thereby driving sustained growth despite the capital expenditure.
