Efficient manipulation of thermal conductivity and fundamental understanding of the microscopic mechanisms of phonon scattering in crystalline solids are crucial to achieve high thermoelectric performance. Thermoelectric energy conversion directly and reversibly converts between heat and electricity and is a promising renewable technology to generate electricity by recovering waste heat and improve solid-state refrigeration. However, a unique challenge in thermal transport needs to be addressed to achieve high thermoelectric performance: the requirement of crystalline materials with ultralow lattice thermal conductivity (κ L ). A plethora of strategies have been developed to lower κ L in crystalline solids by means of nanostructural modifications, introduction of intrinsic or extrinsic phonon scattering centers with tailored shape and dimension, and manipulation of defects and disorder. Recently, intrinsic local lattice distortion and lattice anharmonicity originating from various mechanisms such as rattling, bonding heterogeneity, and ferroelectric instability have found popularity. In this Perspective, we outline the role of manipulation of chemical bonding and structural chemistry on thermal transport in various high-performance thermoelectric materials. We first briefly outline the fundamental aspects of κ L and discuss the current status of the popular phonon scattering mechanisms in brief. Then we discuss emerging new ideas with examples of crystal structure and lattice dynamics in exemplary materials. Finally, we present an outlook for focus areas of experimental and theoretical challenges, possible new directions, and integrations of novel techniques to achieve low κ L in order to realize high-performance thermoelectric materials.

Additive manufacturing (AM) has progressed rapidly in recent years, thanks to its versatility in printing complex and intricate shapes. Very recently, it has also been making inroads into functional and energy materials. On the other hand, thermoelectrics is a relatively mature field, with well-established understanding and design, especially on the materials level. However, complexities in device fabrication and scalability issues have greatly hindered thermoelectric (TE) applications. In this Focus Review, we discuss the advent of AM as a timely and important tool not only to overcome the scalability issues but also to achieve shape intricacies and conformability for flexible and wearable applications. In particular, direct ink writing (DIW), a subset under materials extrusion methods, holds great promise as a versatile fabrication technique for integrated TE devices. More importantly, we discuss the great promise of “engineered nanostructuring” using DIW as a new paradigm to improve TE performance beyond intrinsic properties.

“…However, 1D perovskites have another challenge to overcome for scalable optoelectronic applications, which is the precise positioning with a preferred orientation, alignment, and/or assembly of as-synthesized nanowires, similarly to the challenge for the conventional inorganic nanowires. To achieve the precise spatial arrangement of nanowires, several approaches have been introduced, [37] such as electrostatic micromanipulation, [38,39] microfluidic assembly, [40,41] Langmuir-Blodgett assembly, [42] and dielectrophoresis. [43] Unfortunately, these approaches are not directly adoptable for the perovskite nanowire assembly in consideration of the chemical instability related process incompatibility.…”

Low-dimensional nanostructures of halide perovskites have been receivingextensive research interest for their superior optical, electrical, and stability characteristics over their conventional bulk counterparts. In particular, the unique surficial characteristics of well-defined 1D nanowires have shown high feasibility for high performance optoelectronic applications. The key aspect of endorsing this nanoscale form factor in practical applications lies in securing dimensional uniformity and controllability in large scales, which generally requires complicated lithographic procedures. In this work, a simple, rapid, and widely applicable strategy for the direct synthesis and printing of wellaligned nanowire arrays on a large scale is demonstrated. By employing blade coating methods with sophisticatedly controlled stick-slip motions, periodically resolved transverse 3D meniscus enables uniform directional growth of highly crystalline CsPbI 3 nanowires without the need for templates. A systematic investigation of morphological evolutions with respect to kinetic processing variables is conducted, along with a comprehensive suite of structural and optical analyses for the synthesized nanowire arrays. A single nanowire photodetector is employed to demonstrate the superiority and applicability of the fabrication strategy. Finally, a 2D image recognition is demonstrated by using an array of photodetectors fabricated via a fast (<2 min) direct printing of nanowire arrays on wafers.
