常见错误

❌ 错误:heterojunction is a verb.
✓ 正确:heterojunction is a noun.

错误地将 heterojunction 用作动词,它实际上是名词,指一种结构或界面,应作为主语或宾语使用。

❌ 错误:heterojunction between same materials.
✓ 正确:heterojunction between different materials.

错误地描述异质结为相同材料之间,异质结特指两种不同半导体材料形成的界面,需强调材料差异。

近义词辨析

homojunction

homojunction 指由同种半导体材料形成的结,而 heterojunction 涉及不同材料,常用于对比研究界面特性。

A homojunction has uniform material properties, whereas a heterojunction introduces band discontinuities.

interface

interface 泛指任何两种物质或系统之间的界面,更通用;heterojunction 特指半导体异质结,具有特定的电子学含义。

The interface between metal and semiconductor is studied, but the heterojunction focuses on semiconductor-semiconductor junctions.
