2022年3月20日 · Cross-sectional transmission electron microscopy (TEM) images of Pd/WSe 2 (upper panel of Figure 2a) show apparent damage to the topmost WSe 2 layers, which we believe is the main reason for Fermi-level pinning, as reported in previous studies.

2025年2月26日 · Subsequently, cross-sectional transmission electron microscopy (TEM) was employed to examine the structure of the gate stack in the p-type WSe 2 FET. In the TEM image shown in Fig. 5, the WSe 2 layer, gate dielectric, and Al gate are clearly distinguishable. This TEM image reveals an atomically sharp and flat interface.

As a proof-of-concept, field effect transistors (FET) with an in-situ grown WSe2 channel across Au contacts are fabricated, demonstrating a 2D semiconductor transistor via a transfer-free method...
