Controllable Ge Hut Wires With Mobilities Exceeding 20 000 cm2 V−1 s−1
The controlled growth of germanium hut wires on patterned SiGe/Si(001) substrates is reported. These self‐assembled nanowires achieve a record hole mobility of 22 900 cm2 V−1 s−1 at 4.2 K. Remarkably, conductance quantization is observed at a channel length of 1.9 µm, highlighting their exceptionally low disorder and paving the way for scalable, high ...

Inspired by the Mexican jumping bean, this study presents a centimeter‐scale, electronics‐free robot that merges principles from both the animal and plant kingdoms. A thermo‐responsive actuator mimicking larval motion, enclosed within a uniquely shaped plant‐seed‐inspired shell, generates jumping, rolling, flipping, sliding, and climbing through ...
