It exhibits pronounced \u003c\/span\u003e\u003cstrong\u003ein-plane anisotropy\u003c\/strong\u003e\u003cspan\u003e in electrical, optical, and vibrational properties, and is a \u003c\/span\u003e\u003cstrong\u003ep-type semiconductor\u003c\/strong\u003e\u003cspan\u003e with an indirect, layer-tunable band gap (~0.5 eV in bulk, widening in few-layer form).
