Here, we present a Ge based reconfigurable transistor, capable of dynamic run-time switching between n-and p-type operation with enhanced performance compared to state-of-the-art Si devices. Thereto, have monolithically integrated an ultra-thin epitaxial and defect-free layer on insulator platform. To evade the commonly observed process variability Ni-germanides, Al-Si-Ge multi-heterojunction contacts been employed, providing stability required equal injection capabilities for electrons...
Reconfigurable field-effect transistors (RFETs), combining n-and p-type operation in a single device, have already shown promising simulation results for enhancing performance and functionality conventional devices further enabling novel adaptive computing concepts. With recent advances the formation of high-quality monolithic single-crystalline Al-Si Schottky contacts providing reproducible way to fabricate RFETs with highly symmetric operation, we are now able demonstrate their integration...
Abstract Reconfigurable field‐effect transistors, capable of being dynamically programmed during run‐time, overcome the static nature conventional complementary metal‐oxide semiconductors by reducing transistor count and circuit path delay. Thereby, SiGe Ge are predicted to boost drive currents, switching speed reduce power consumption. Nevertheless, Ge‐based reconfigurable prototypes have so far fallen short in reaching both promised performance due interface instability their contacts gate...
Fine grain reconfigurability carried out at the transistor level, i.e. ability to switch between n- and p-type operation, offers new possibilities for highly efficient logic gates. In particular, XOR- Majority gate circuit implementations can considerably benefit from reconfigurable transistors, as they require less than half of count needed in conventional static CMOS technology. Using a total eight on-state symmetric field effect transistors fabricated monolithic Al-Si heterostructures, we...

Temperature dependent bias spectroscopy utilized map electronic...
Implementing only tens of nanometer-thin Ge and Ge-rich SiGe nanosheets on SOI is expected to boost performance metrics next-generation electronic devices, such as reconfigurable field effect transistors [1]. However, an inherent lattice mismatch between Si drastically limits the thickness high-quality layers a few monolayers, i.e., far too thin for practical nanosheet device applications. Thus, date, many prototype nanoelectronics concepts are based nanowires' vapor-liquid-solid (VLS)...
