Abstract Polymer semiconductors hold great potential as active materials in (opto)electronic, thermoelectric, and biomedical devices. Their charge transport performance has seen tremendous progress, with mobilities exceeding 1 cm 2 V −1 s for a variety of donor‐acceptor copolymers. Nevertheless, injection at the metal/polymer interface is still rather ineffective poorly understood. In field‐effect transistor, this process manifested by contact resistance ( R c ) which, polymers, several orders magnitude higher than their inorganic counterparts. Therefore, an in‐depth investigation metal/donor‐acceptor polymer systems sought‐after. Here, low‐temperature dependent model isoindigo copolymer‐based transistor are studied. The tuned functionalizing electrodes different thiolated self‐assembled monolayers (SAMs). devices SAM‐functionalized generally lower exhibited weak temperature dependence. Counterintuitively, functionalized SAMs expected to lead apparently unfavorable energy level alignment displayed lowest . Fermi found be pinned all encompassed interfaces. An energy‐level modeling employed understand behavior. findings reveal that simply looking levels does not necessarily reduced

Thermoelectric technology experienced rapid development over the past 20 years, with most promising applications being in both power generation and active cooling. Among existing thermoelectrics, tin selenide (SnSe) has had particularly owing to unexpectedly high thermoelectric efficiency that been continuously established decade. Several transport mechanisms strategies used interpret improve performance of SnSe have important for understanding developing other material systems SnSe-like characteristics. Similar building commercially viable SnSe-based devices requires advances device service stability. Further optimization across all should enable play a critical role future global energy landscape.

The recently discovered metal-like room-temperature plasticity in inorganic semiconductors reshapes our knowledge of the physical properties materials, giving birth to a series new-concept functional materials. However, current plastic are still very rare, and their performance is inferior that classic brittle semiconductors. Taking bismuth telluride (Bi 2 Te 3 )–based thermoelectric as an example, we show antisite defects can lead high-density, diverse microstructures substantially affect mechanical thus successfully transform these bulk from plastic, leading high figure merit up 1.05 at 300 kelvin compared with other semiconductors, similar best We provide effective strategy plastify display good excellent functionality simultaneously.

Abstract Controlling the microstructure of semiconducting polymers is critical for optimizing thermoelectric performance, yet remains challenging, requiring complex processing techniques like alignment. In this study, a straightforward strategy introduced to enhance properties semi‐crystalline polymer films by incorporating minimal amounts nucleating agents, method widely used in traditional industries. By blending less than 1 wt% N,N′‐(1,4‐phenyl)diisonicotinamide (PDA) into poly(2,5‐bis(3‐alkylthiophen‐2‐yl)thieno[3,2‐b]thiophene) (PBTTT‐C14), controlled modulation crystallization behavior achieved, resulting reduced structural disorder and enhanced charge carrier mobility. Systematic investigations reveal that an optimal PDA loading 0.9 increases degree 45% compared pristine PBTTT‐C14 films. Under these optimized conditions, PDA‐modified exhibit maximum electrical conductivity 1,894 S cm −1 power factor 176 µW m K −2 , showing improvements 96% 433%, respectively, over doped These gains are attributed synergistic effects chain extension grain boundary resistance, which collectively transport efficiency. Additionally, ion exchange doping found maintain high concentration while preserving crystallinity PDA, paving way advanced materials next‐generation polymer‐based electronics.
