A brittle solid that is also semiconductive could belong to several classes of materials, but one common category is **metal oxides**. Specific examples include:
1. **Zinc Oxide (ZnO)**: A semiconductor with wide applications in electronics and optoelectronics, known for its brittleness.
2. **Tin Oxide (SnO2)**: Another semiconductor with good electrical conductivity and is often used in gas sensors and transparent conductive films.
3. **Cadmium Sulfide (CdS)**: A semiconductor known for its use in solar cells, which is also brittle.
In addition to metal oxides, some **ceramics** or **compound semiconductors** may also fit this description, such as:
- **Gallium Nitride (GaN)**: A semiconductor with beneficial properties for electronic devices, though it is typically more brittle than traditional materials.
- **Silicon carbide (SiC)**: Used in high-temperature applications and semiconductor devices, though it is harder than typical brittle materials.
More broadly, many **II-VI materials** (such as cadmium telluride, CdTe) and certain **nanostructured materials** can also be brittle and semiconductive.
If you can determine more specific properties or conduct tests (such as conductivity measurements, X-ray diffraction, or spectroscopic analyses), you might refine the identification further.
