Abstract: Integrated circuit structures having internal spacers for 2D channel materials, and methods of fabricating integrated circuit structures having internal spacers for 2D channel materials, are described. For example, an integrated circuit structure includes a stack of two-dimensional (2D) material nanowires. A gate structure is vertically around the stack of 2D material nanowires. Internal gate spacers are between vertically adjacent ones of the stack of 2D material nanowires and laterally adjacent to the gate structure. The 2D material nanowires are recessed relative to the internal gate spacers. Conductive contact structures are at corresponding ends of the stack of 2D material nanowires, the conductive contact structures adjacent to the internal gate spacers and vertically overlapping with the internal gate spacers.

Abstract: The capillary transfer technology presented here represents a powerful approach to transfer soft films from surface of liquid onto a solid substrate in a fast and defect-free manner. The fundamental theoretical model and transfer criteria validated with comprehensive experiments and finite element analyses, for the first time provides a quantitative guide and optimization for the choice of material systems, operating conditions and environments for scalable on-demand transfers with high yield. The intrinsically moderate capillary transfer force and externally selectable transfer direction offer robust capabilities for achieving deterministic assembly and surface properties of structures with complex layouts and patterns for potentially broad applications in the fabrication of flexible/stretchable electronics, surface wetting structures and optical devices.

Abstract: Systems and methods are provided for a battery management system (BMS) having a protection circuit. In one example, a vehicle battery system may include the BMS, the BMS including a cutoff circuit coupled to a short-circuit protection circuit, and a battery pack, wherein the short-circuit protection circuit may include a diode array, cathodes of the diode array being coupled to a positive terminal post of the battery pack and anodes of the diode array being coupled to a negative terminal post of the battery pack. In some examples, the cutoff circuit may further be coupled to a reverse bias protection circuit including a switchable current path arranged between a control input of the cutoff circuit and an output of the cutoff circuit. In this way, the vehicle battery system may be protected from unexpected voltage conditions via the BMS redirecting and dissipating excess current away from the cutoff circuit.

Abstract: The present embodiments relate to a write head design with a patterned hot seed (HS). Particularly, the HS can be patterned as part of a multi-step patterning process that can partially or completely remove portions of the HS at multiple sides to form various designs. For example, the HS can have a two-step cliff design, etching multiple steps around an un-patterned center portion, and a flared angle. The designs of the patterned HS can improve write head performance.

Abstract: A genetically-modified rat having a PKHD1L1 gene with a point or other mutation and a construction method thereof are disclosed. A CRISPR/Cas9 system knocks the PKHD1L1 gene into a mouse source, and a codon changes from TTA to TCA to construct the mutant PKHD1L1 gene. The genetically-modified rat can be applied to epilepsy pathogenesis studies and design and testing of new anti-epileptic drugs. Methods for detecting abnormal cortical excitability and detecting an epileptic phenotype of an animal can use the genetically-modified rat. A somatosensory evoked potential is used to detect whether the genetically-modified rat has an abnormal cortical excitability phenotype, so as to confirm whether the rat can be a successful model for testing anti-epileptic drugs. The method can detect abnormal cortical excitability and verify the effectiveness of anti-epileptic drugs or treatments.
